Shock attack across rivers 1/3 of AV

[rader]

The new rule says that units will shock attack unless "1/3 of the unmodified AV of the defending units have crossed the hexside in a previous turn". Ok, so how reliable is the memory on this? Say a defender has 300 AV. Can I send 25 one turn, 50 the next turn, 25 the third turn, and then from that point on, no units will shock attack (i.e., I've paid my dues)? Or does the entire 1/3 have to cross at the same time?

Anyone know?

Ouch, my head hurts! [;)] I doubt there will be many here who could answer that one...

[rader]

Only someone who has access to the code... but you would think that it would be important to know something like this!

I can't give you a definitive answer as I try not to make an opposed river crossing in drips and drags. However my take on this issue is that "memory" is not really in play here. To use your example (which of course is overly simplified) I would operate on the basis that the game code makes the following assessment:

(A) Day 1, contact made, checks to see if river crossing rule applies, compares defender's 300 AV with attacker's 25 AV present at riverside hex - determines attacker must make auto shock attack

(B) Day 2, contact maintained, checks to see if river crossing rule applies, compares defender's 300 AV with attacker's 75 AV at riverside hex - determines attacker must make auto shock attack

(C) Day 3, contact maintained, checks to see if river crossing rule applies, compares defender's 300 AV with attacker's 100 AV at riverside hex - determines attacker is not required to make auto shock attack

Of course these AVs would not apply in the actual game because of casualties incurred by both sides on days 1 and 2. In particular, the attacker should incur more casualties so that the unmodified AV after combat on day 2 might mean that the defender still has 270 AV but the attacker might only have 20-30 AV thus necessitating a crossing on day 3 of 60-70 AV to prevent the auto shock attack rather than your positied linear 25 AV.

Hope this helps, but as you said, it really needs someone with access to the code to give a definitive and accurate reply to your question.

Before a unit moves into the hex the raw AVs in the destination hex are compared and if less than or equal 1/3 or if hexside is enemy controled then that unit must shock attack.

Are you sure? This is not what the rule says. The rule is specific to the hexisde. For example, if units cross from different hexsides (all across river), I don't think that would satisfy the requirement.

Attacking from a different hexside does trigger another shock attack.

This is key.

Ok, I think I understand, but it's not exactly as stated: "when crossing a river into a hex all units entering should shock attack in the turn they
cross, unless 1/3 of the unmodified AV of the defenders has already crossed from that hex sidein a previous turn."

This implies that it keep a running tally of AV that has crossed each hexside over time, but this would require memory in the programming (at the extreme, a counter variable for each hexside on the map), so I doubted this was how it worked.

Effectively, it should say: "when crossing a river into a hex all units entering should shock attack in the turn they
cross, unless 1/3 of the unmodified AV of the defenders (was present in the hex before the move or they are crossing a hexside they didn't control at the start of the turn)".
