I would agree with level 5 being only Sevastopol-like forts, and equally hard to make. Layers of Level 4 forts are enough. It is a good 'game' wherein both players want to think ( or they won't play) that it is possible to win or lose irrevocably before winter 43.

So it sounds like the construction for most if not all of the Spring was under the old 1.03 rules. I'm betting you would see many fewer 4 and 5 forts if you had the 1.04 changes for all of 42.
Joel - I hope you are right that the 1.04 changes will help reduce the forts. Most of the PBEM campaign we've been playing are prior to 1.04. Will be interesting to see how some of the newer post 1.04 campaigns fare.
I realize its a tough balance and reducing fortification capabiltiy too much may let the panzers run too wild in 41-42 and the Soviet Steamroller in 43-45. I think counterweight to the lesser forts are the increased attrition and stringent supply to have offenses peter out quicker after a 100+miles. HQ buildup is a great concept and in the right direction, but even that can't overcome multiple level 3-5 fortifications in depth.
One of the comparisons we were asked to look at in a campaign started in Jun 41, was to see how it stacked up in forces avail by the time the game reached the 1942 Campaign. I think we need to not only look at the forces, but the amount of fortifications on the map as well. In mine, granted, mainly not in version 1.04, there is just too many.

I agree that in 1.03 there were too many high level forts. That's why we made the 1.04 changes. If you look at the formulas, you'll notice that we didn't change the low level fort building, but once you get to level 2 it gets a little harder to get to 3. Then the big changes kick in at the higher levels, where not only is the building time doubled, it can also be slowed further by missed admin rolls. Now if you looked at the time it takes to build the various fort levels, almost all of the time is going into getting from 3 to 4 and from 4 to 5, so doubling these times should be a significant change. We need to see more games with 1.04 fort building rates before we can say it's enough or if more changes are needed. Bad weather fort building of level 4 and 5 forts should be very very slow. I just checked an AI test game I ran last month and saw that even with 3 divisions in a Moscow hex, it was looking like it would take about 40 turns to get from level 4 to level 5. In two months another Moscow hex got about 40% of the way from level 3 to level 4. This was during the March to May 42 time frame. That's just one sample and the AI was no doubt going slower than a human player, but I think we need more data to decide for sure whether we've already fixed the fort issue.

Think 1.04 has things on the right track Joel. But my gut tells me its going to take some more tweaks. Really appreciate all you guys do!

Right now most German players do the Rumanian and Riga first turn gambits neither of which is historical.
I know of the Riga gambit (not really a gambit because you don't sacrifice anything) but what is the rumanian first turn gambit ?

I hate to jump into this discussion as it looks like its mostly for those playing the axis. I am the opponent IdahoNYer is playing in the campaign game with all the forts.
I agree that some of the fortifications seem to be a bit much. It might help if the game gave an explanation as to what the levels approximated, ie is level one simple fighting positions that can be dug in a night of hard digging, and is level 2 the same fighting positions with good overhead cover and some wire and mines and nicely drawn fire plans etc? I would think that in six months some pretty hefty positions could be dug, especially with lots of engineers.
Here is an example of what the Leningrad defenses were composed of that I pulled off the net.
"On June 27, 1941 the Council of deputies of the working people of Leningrad decided to mobilize thousands of people for the construction of fortifications. Several defences were built. One of the fortifications ran from the mouth of the Luga River to Chudovo, Gatchina, Uritsk, Pulkovo and then through the Neva River. The other defence passed through Petergof to Gatchina, Pulkovo, Kolpino and Koltushy. Another defense against the Finns was built in the northern suburbs of Leningrad. In all, 190 km of timber blockages, 635 km of wire entanglements, 700 km of anti-tank ditches, 5,000 earth-and-timber emplacements and ferro-concrete weapon emplacements and 25,000 km of open trenches were built by civilians. Even the gun of the cruiser Aurora was mounted on the Pulkovskiye Heights to the south of Leningrad. However, when Soviet troops of the North-Western Front in the end of June were defeated in the Baltic Soviet Republics, the Wehrmacht had forced its way to Ostrov and Pskov. On July 10 both cities were captured and the Germans reached Kunda and Kingisepp whereupon they advanced to Leningrad from Narva, the Luzhski region, and from the south-east and also to the north and south of the Lake Ilmen in order to isolate Leningrad from the east and to join the Finns at the eastern bank of Lake Ladoga."
All that was done in what two months? What would it look like in six months of uninterrupted digging?
However, the Russian troops are so brittle, too brittle in my opinion in 41 and 42, that without these entrenchments, its just too easy for the axis. Unless the supply can be restructured in 42 to prevent the Germans from having the ability to attack virtually everywhere and with HQ build up, and if the Russians are not beefed up a bit the Germans are too powerful in 42.
So I am not sure we are really arguing, or debating, what the fortifications should look like, or how quickly they should be built. What the debate is really about, is how tough the Russians should be in 42, and how can the game be structured to allow for historical gains by the Germans in 42. Of course this should be relative. Some games, where the Russians did extremely well in 41, and saved much of their army and factories, the Russians should be tougher come 42. In games where the Germans made big gains, Russian losses were exceedingly high, like in my game, the Germans should have an easier time of it in 42.
In the end, in my humble opinion, while we want the game to follow the historical possibilities, we shouldn't force it to follow the same path as in the history books. Could the Germans have been stopped in 42 short of Stalingrad? Maybe, but probably not. Likewise, could the Germans have launched attacks both in the south towards Stalingrad and the Caucasus and made an attack against Moscow? Maybe, but the supply situation would probably have prevented such an ambitious undertaking.
As far as the fun of the game, I think everyone would like to see a fluid 42. If that's the case, make the entrenchments lower, and harder to get, but bump the Russians strength, so its not a walk in the park for the Germans, and so that they will have to choose a focus rather than attack everywhere as in June 41.

The outstanding issue for forts right now in my book is how long they stick around when the troops have left.
In late 42, I've still got belts of forts behind my lines dug six months ago, even though no units have been any where near.
I think the decay factor for unoccupied fort levels should be much higher. In fact, a fort should ideally take something like a 10% hit even when one unit takes over from another sitting in the fort hex during the same turn. The incomming unit wouldnt be so used to the layouts, fire zones, ranges, etc. Especially though weather conditions like mud - I dont think unoccupied trench lines would be in much shape after a couple of weeks of raputista.

I think what Scar said has some bearing (cool avatar pic, too, Scar.)
The Soviets cannot stop the Germans, anywhere in light terrain, without at least a level 2 fort.

I'd personally rather see the Soviet divisions be made a bit better early on, and have forts vastly reduced. As it stands now, every PBEM game I've played is a race to stop fortifications. Even when they reach lvl 2 but are 5-6 hexes deep, any offensive gets beaten to crap within a few turns. I just quit a PBEM Operation Blue scenario, where once I started approaching the Volga I was hitting waves of lvl 2 forts everywhere. I did OK for 2 turns, but by the time I had advanced a few hexes, all my units were around 40% TOE. Some of that was the new reserve system as well. Had Tank Corps coming up (from 7-8 hexes away, no less!) that completely ravaged even my winning attacks.
IMO, game still has massive balancing issues in favor of Soviets.

Thanks heliodorus04, one of my favorite movie characters (Bridge Too Far).
I agree Altaris. The Germans are too powerful in 41, and 42. The Russians are too powerful when considering blizzard effects and current entrenchments. If the Russians got a boost in 41, to make it a little tougher on the Germans, the blizzard effects were reduced, and the Russians were made a lot better in 42, the game would follow a bit more historically.

In the game FITE the same issue was present but was mitigated by the using of resource points to build forts. As a Soviet player you could build some very potent forts but not have them everywhere. That led to a much more fluid game.
I think in this game field fortifications level 1-2 should be free and abundant but levels 3-5 should require the expenditure of some type of commodity. Since our only "money" we can spend in the game is APs that would suffice.
The level 1-2 forts would go away when their creator moved but level 3+ that required APS would stay for others to occupy.
This change would greatly impact the amount of planning that would be needed and add a different dimension and complexity to the game. No more just leaving a carpet of single units down that build up to level 4 forts to later be occupied by 3 units ect...

Because historically the Russians did not construct fortifications in 1942 in the amount we may see in the game does not necessarily mean they did not have the capability to do it. If Comrade Stalin orders you to conduct the Kharkov offensive in the spring, he does not want to see you digging in to the rear.

Level 1 and level 2 aren't that bad. Level 3 requires work, and level 4 and 5 make me ask myself, "why am I doing this?" I kinda like the suggestion Andy has above of level 5 only in urban areas. Heck maybe level 4 or 5 near cities then, the urban areas and adjacent hexes. Anything to stop the Trench warfare feel the game has, which is was around Leningrad for a long time, but not in southern Russia. I also understand this is a two edged sword, so when the 'Russian Steamroller' comes a'knockin' they will have an easier time too.

No, 1st and 4th Panzer Armies get set up to the Moscow area to prevent the destruction of Army Group Center. I usually pull up at Riga and the Don River, moving further would mean I am trading trying to take Stalingrad (with my flanks still being vulnerable) for 1/3rd of my army north of Voronezh being destroyed.
It's really hard to simulate how far the Germans got as we use our troops much more efficiently than they did in 1941-1945. This is pretty normal though, for you grognards who played Fire in the East (GDW Games, the boardgame) we ran into similar issues I am seeing here. I am truly amazed at how far the Germans advanced in 1941-42 historically.

I agree and slightly disagree with you. Putting into game terms: 1) Fortifications around Leningrad were indeed impressive, but not out in the middle of non-urban areas. I have been reading more accounts, and often, in 1941, Russian barricades consisted of their comrades they stacked up to hide behind (there's a visual for ya). In constrast, by the Russian Offensive in November, 1942, both sides (especially the Soviets) would blend into the terrain to be virtually impossible to find.
2) The Brittleness of the Russian Army. Varies area to area and at what point in time. The 1st 4 turns of the game, I don't mind seeing Russian formations having a chance to surrender, north of the Pripet Marshes. In the south, you would have to dislodge them from the get-go. The difference, unit morale and experience. It may seem a bit gamey, but there could be certain thresholds for units in terms of experience and morale where units are not so brittle. You could have the early success the Germans did achieve, followed by the stiffening resistance they did face.
This is such a tricky balancing act, and I am glad someone is trying to make it happen. Thank you.

I think that might have been me. If you think Maginot Line / Atlantic Wall / Stalin Line, these were all big projects with top-level backing and required the diversion of huge resources from the economy. They weren't built by the troops on the front line or even by their combat engineering units.

The thing is level 4 and 5 forts aren't supposed to be those Maginot type fortifications. There was talk of making a level 6 fort just for Sevastopol that starts the game with that level of fortification, but it never happened. Regardless though, an ap cost does sound like a good idea for at least level 5.

Food for thought from game manual for V for Victory (WitE of the 1990's - wow it's so many years from now):
Field Fortifications
There are two types of field fortifications that units may construct during the game. Both of them benefit defending units only; there is no advantage to attacking out of a hex that contains a field fortification. A unit that is "dug in" has foxholes, weapons pits, pre–registered targets, pre–planned fields of fire, and a generally planned, prepared and organized defense. A "fortification" represents all these things plus minefields, some barbed wire, the beginnings of a trench system, and a few simple log and earth bunkers.
Each field fortification appears on the map as the uppermost "unit" in its hex. (These are really just markers, not units.) The "size" of a field fortification is indicated by the number at the bottom of the marker, and that size is the number of companies that may gain full benefit from being in the same hex with it. Each battalion equals 3 companies for this purpose, so a size 9 field fortification can "contain" 9 companies (or 3 battalions), which is the stacking limit for most of the hexes on the map.
Field fortifications may be enlarged by having the same or other units build another one in the same hex. If more than one unit is constructing a field fortification in a hex at the same time, only one "building" marker is shown. Larger field fortifications have no additional effect except that more units may benefit from them.
Field fortifications may never move, and benefit only friendly units in the same hex with them. Once the field fortification is completed, the unit that built it is free to conduct other activities and/or move away, and other friendly units are free to move in and benefit from it. However, a field fortification is automatically removed from the map at the end of any turn that there are no friendly units in the same hex with it.
Most defensive positions are actually directional in nature; i.e., they face a particular direction and provide maximum benefit to the defender only if he is attacked from that direction. Each field fortification therefore represents a planned and prepared defensive line which, in reality, would have a significant effect only if attacked from the "front." Although they are realistic, directional combat effects are typically found only in tactical– level games, and would be a considerable added complication in an operational–level games such as the V for Victory™ series. We considered expanding the game system to include directionality and decided that, at this scale, it is not worth the trouble; very nearly the same result can be achieved in a much simpler way. V for Victory™ games assume that, when initially built, a field fortification faces the enemy, or at least the direction the enemy is most likely to approach from. As long as the position is continuously occupied, that directionality is preserved, and the probability that the field fortification will be beneficial remains high. However, if a position is ever captured or abandoned, its original directionality is presumed to be lost, and whatever remains of the field fortification is assumed to be facing the wrong way, or located in the wrong place within the hex, to be of much use to later occupants of the hex. This argument applies especially to captured positions.
Digging In
All units may dig in except those that are adjacent to an enemy unit, or those that are located in a located in a swamp, bunker, beach bunker, or fortress hex. It normally requires two turns to dig in. To begin, select the unit and press the letter "F" on the keyboard. (Or, you can open the Command Box for that unit, make sure the unit is assigned one of the three "defend" options, click on the "dig in" symbol, and then close the Command Box.) This causes a "digging in" marker to appear as the top unit in that hex on the map. To finish digging in, "dig in" orders must be assigned again on the next game–turn; as a convenience, the game automatically does that for you, so that once a unit begins to dig in, it continues to do so until you change its orders. If you assign orders other than "dig in" on the next turn, the process is either interrupted or canceled. If the unit moves out of the hex, the process is canceled, and the digging in marker is removed from the map. The process is merely interrupted (and may be completed on a later turn) if the unit is attacked by artillery/naval/air (with no enemy units adjacent), participates in combat as an attacker or defender without leaving the hex, if the unit remains inactive in order to recover from fatigue or disruption or to receive replacements, or if the unit is an artillery unit and conducts a fire mission. If an enemy unit moves adjacent to a unit in the process of digging in, the process is canceled and the "digging in" marker is removed from the map.
When dug in units are defending in a hex that contains a dug in marker large enough for all of them, it multiplies their defense strength by 1.5, their antitank strength by 1.25, increases their morale by 1, and halves the strength of incoming artillery/naval/air attacks. If the dug in marker is not large enough to contain all the units in the hex, it multiplies their defense strength by 1 + (0.5 x (marker size/stack size)), it reduces the strength of incoming artillery/naval/air attacks by a proportional fraction, and it has no effect on the antitank strength or the morale of the defending units.
The advantages of being dug in do not apply to units that are conducting probes, assaults, all–out assaults, or any type of movement.
In Velikiye Luki, during hard freeze and deep snow ground conditions, non–engineer units may dig in only in village and city hexes. Engineer units may still dig in when they are in clear terrain or forest hexes, but this takes twice as long as normal (i.e., four game–turns). Both engineer and non–engineer units may dig in when they are in lake hexes only during deep snow conditions (when the lake becomes clear terrain for all purposes).
Fortifications
Fortifications are constructed in the same manner as digging in, except that the first fortification marker in a hex may be built only by an engineer unit, and constructing the first fortification in a hex normally requires four turns. Like digging in, a fortification may not be built or enlarged in a bunker hex, or in a hex that is adjacent to an enemy unit. Unlike digging in, a fortification may be built or enlarged in a swamp hex, but this takes twice as long as normal (i.e., eight game–turns).
When units are defending in a hex that contains a fortification large enough for all of them, it multiplies their defense strength by 2, their antitank strength by 1.5, increases their morale by 2, and halves the strength of incoming artillery/naval/air attacks. If a fortification is not large enough to contain all the units in a hex, it multiplies their defense strength by 1 + (fortification size/stack size), their antitank strength by 1 + (0.5 x (fortification size/stack size)), it halves the strength of incoming artillery and air attacks, and it raises the morale of the defending units by 1.
Like being dug in, these advantages do not apply to units that are conducting probes, assaults, or any type of movement.
In Velikiye Luki, during hard freeze ground conditions, engineer units may still construct fortifications in all types of terrain except lakes, but this takes twice as long as normal (i.e., eight lake hexes during hard freeze conditions, they may be constructed on lake hexes during deep snow (when the lake becomes clear terrain for all purposes). This also requires eight game–turns.
Note that in Velikiye Luki, for the purpose of constructing field fortifications, construction battalions are engineer units.
Digging In and Fortifying in the Same Hex
A hex may not contain a completed dug in marker if it also contains a completed fortification, and vice versa. Both may be under construction at the same time (in which case the fortification is the one that appears), and either may be under construction in a hex that contains a completed one of the other (in which case whichever one is completed is the one that appears).
When a fortification is completed in a hex that already contains a completed dug in marker, the size of the newly–completed fortification is immediately increased by one–half of the size of the dug in marker (fractions rounded down), and the dug in marker is removed. For example, if a hex contains a completed dug in marker of size "3," and a building fortification of size "1," when the fortification is completed, it becomes size "2," and the dug in marker is removed.
Units may be assigned to dig in a hex that already contains a completed fortification. However, in this case the dug in marker never appears on the map; when the units are finished digging in, the already–complete fortification marker is enlarged instead. The amount that the fortification is enlarged by depends on the size of the unit that is digging in; a company–sized unit enlarges the size of the fortification by 1, and a battalion–sized unit enlarges the size of the fortification by 2. For example, if a hex contains a completed fortification marker of size 1, and a battalion–sized unit digs in the hex, when it is finished digging in, the fortification marker is enlarged from size 1 to size 3. This process may be repeated to enlarge the fortification to size 5, and so on.
Please bear in mind that even though authors of that game consider V4V as operational game (as WitE authors say about their game) the scale there was 1km per hex, 4 hours per turn and units (counters) were of battalion and company level, so a division would consist of 10-15 counters (Soviet divisions were smaller, as one rifle regiment was one counter). So they made a full length game about Velikiye Luki, whereas in WitE it's just a micro-scenario
However there are interesting ideas here about fortifications. First of all, fortifications besides their level, have size. So it would take 4 turns per level x 15 levels = 60 turns for a company of engineers to build a maximum size of field fortifications in a city hex - that's 10 days - that's counted without fatigue - they would tire after a day or two and building would take event longer that that. And that would be only for an area 1km in diameter. Of course aided by 3 battalions of infantry they would complete the work much faster. Anyway, it was good to have size of fortifications - you wanted to have large fortification and fast - you had to put a lot of men with shovels there.
Second great idea was separating digging in from field fortifications that only engineer units could start. Regular units without engineer help could only dig in.
Third great idea was that preparing trenches requires no bullets whizzing over your back, so it's impossible to improve them once you are in contact with the enemy.
Fourth great idea was that there were 2 more "levels" of fortifications: bunker terrain and fortress terrain and they were not buildable which was ok, considering the length of scenarios in V4V - at most 3 months of time. They were much better than digging in and field fortifications but there were only so many as the designers allowed in proper places.
Fifth great idea was that fortifications disappeared after you left them - a good balance between details and simplicity - this represented that fortifications are directional in nature and once a fighting position was left, they would be of little use should a frontline reach that hex again.
Interesting are also those notes that say about difficulty of digging in in snow conditions - regular units could do that only in villages and cities.
WitE has of course different scale which changes many aspects, however some could be modeled. Size - this I think is represented by the fact that 3 units would dig faster than one having more "digging factors". Higher level fortifications should require more engineer elements involved otherwise they would be impossible to complete or very slow (so a unit with just a company of engineers should not expect to build higher levels of forts - for really high level you should attach some support engineer units). Building should be very slow when in contact with the enemy of course (it is, but is this really slow or just a little bit slower - I don't know). Units without engineers should be able to build only level 1 fortifications (dig in from V4V), units with engineers should be able to build level 2 (field fortification from V4V), levels 3-4 (bunkers from V4V) should be only possible with an AP cost and some high wait times, and not when in contact with enemy), level 5 should be restricted to pre-war really strong fortifications and not buildable. Once left a fortification should loose at least 1 full level per turn, except fortifications of level 5. Of course that's my interpretation of rules for V4V translated into WitE scale. Yours may vary, I just wanted to show how it was done in another good game, that had a bit different scale though.
