Attacking the PI is a must. You know it, I know it, the guy you are playing knows it. But how to go about it? Yes, you can load up a bunch of ships and damn the torpedoes and go storming in.
I have found through trial and error (mostly error) that in order to conduct an operation effectively in AE, you have to plan well ahead. Much like the real commanders did.
Part I of this essay will be the northern PI. Mindanao will be part II. First off, this is the map (from the allied point of view). There are numerous bases through the PI, but other than Luzon, only a handful are defended. The 4 bases marked "A" on the map contain strong PI units (well, stronger than an empty base anyway). The 2 bases where the allied TFs are (Cebu and Panay) have divisions sized units that have AVs at or near 100. The other 2 bases have regiments with AVs in the low 30s. The unit at Puerto Princesa is a company sized base force and is for all intents a vacant base.
Tinas in AE cant drop on half the map. There are 3 airborne units that start the game. 1 is a parachute regiment that starts in Kagoshima and is out of range until it is moved. The other 2 are SNLFs on Formosa and from their base with Tinas as transport they can only land in these hexes, not beyond.
Other than Manila, there are only 2 level 3 ports on this map and they are labeled "B". Batangas is the name of the one on Luzon. There is a PA division there, another div in the base to the SE, and 2 divisions plus 4 regiments (and misc other support) in Manila itself. An attack here would require a major effort.
Busuanga is undefended. It can be taken by para assault in the first turn, or the 2nd turn by fast transports. It is on his path out of Subic Bay. It is perfect! Well, not quite perfect. There isnt an airbase there. So you will need an airbase close enough to provide CAP cover, or you do it with floatplanes.
The Purple boxed bases all have level 1 airfields, which is all you need for CAP. The red ones are level 2+ meaning they can be used as strike bases. The only strike bases in the PI are on Luzon, Mindanao, and 2 islands: Panay and Jolo. Jolo is undefended but out of parachute range at start. You can air transport a para to Cam Rahn Bay and drop on Jolo from there. "C" is Taytay, the closest CAP field to Busuanga.
Now in this game I made several mistakes. Well not mistakes par se, I just fell off the learning cliff [;)]. My first mistake was I looked at the above map and saw a nice clear valley all the way to Manila / Clark so I decided to land both the 48th and the 16th at Aparri foregoing everything else. Well it was such a cluster fark that the 48th never did get unloaded, so I ended up diverting it south where the 16th normally would have landed.
So
lesson 1 is dont plan on more than 1 regiment per day unloading at a beach / level 1 port.
Lesson 2: I waited a day before beginning loading the 48th as I didnt want to get hit by a suicide run by the Brit DDs in Hong Kong again. Keep a CL or 2 with a handful of DDs with a react of
ZERO (so they wont leave the TF they are escorting), and drive on.
Lesson 3: I took Taytay by fast transport carrying an airfield co which in and of itself is fine. But I didnt send a follow-up force with supplies. I also didnt allocate a CAP to the fast transport group and they wasted a day or 2 because of air threat (TFs will retreat from air or surface threat if they dont have enough cover force).
Lesson 4: I didnt send tankers or tenders with my Busuanga landing force and too few supplies. I had a HQ and naval support for repairs, but I had no way to reload or refuel my ships after they got there.
Grabbing a level 3 port in the area is important, it saved several of my ships. But you also need to defend it (after he hit me with PTs that first time I assigned a DD squadron there to protect it). And if you want to use it for an operations base you need to have the tenders in there as well. You need an AD to reload torps at a level 3 port (or a truckload of nav support guys - in the hundreds) and a level 3 port with no nav support can only reload 3" guns. With 50 nav support you can do 6". I had 1 base force (about 120 nav support) and a naval HQ (about 240 more). With that many nav support I could reload up to 8" guns and any torpedo EXCEPT the Long Lance. A 2nd base force would have allowed it (you need 424 nav support at a level 3 to rearm Long Lances).
Or simply put an AD in the harbor. One thing to note about tenders in AE: you need supplies on the tender for it to function.
Lesson 5: Actually I knew this already but it was confirmed this game - get eyes out there. Even a level 1 port can operate a float or patrol plane. Grab a few in key areas and get your Jake and Mavis search planes out there, but again, dont forget to bring supplies also.
