I’m afraid I can’t quite answer the first part of the question. My Axis and Allies “lingo” is, well, sub-par. OOB, Alpha +2 etc., those terms are foreign to me. I can tell you that we are playing with the rules listed in the Europe edition rulebook, minus technology.
The official objective of each coalition is to achieve the capture of eight victory cities, or the Axis capitals. However, if the Axis can knock out one of the Allied powers (Russia, mostly) and the remaining nations aren’t in a position to invade the France or Italy, we’ll usually just call it an Axis victory.
Or, if you were referring for the method of attack for each nation in itself, I’ll tell you that as well. I’ll invade the USSR on G1, put a factory and airbase in Finland on G2 and start building up there. Germany tries to crunch Leningrad on G3 or G4, using infantry from Finland, tanks from the heartland Germany, and, mostly, an airforce that Germany spent the first two or three turns investing in. The infantry cushion the blow, and I get off with the majority of my Luftwaffe. After this, infantry that had previously attacked Bessarabia and Eastern Poland had moved into range of Moscow. I attack, usually on G4 or G5, with the roughly six infantry and four tanks, not to mention the 16-plane (mostly strat. bombers) airforce.
I have also used SeaLöwe a few times, and once sacked England on the second turn. This is perhaps the most prominent example of Allied blundering in my games, this gross misallocation of resources (fighters, not infantry).England always gives Germany a huge advantage, and with the extra IPC’s, and freedom to concentrate on one front, I can take Russia pretty quickly. If SeaLöwe is used, Germany also starts to build many factories, after this victory, particularly in Slovakia and Romania.
As for Italy: if Germany drives for England, they press hard in Africa, with typical success, and both deprive England of recourses, and get fairly uncontested land once London falls. In case of Barbarossa, Italy lands two infantry, an artillery and a tank in the Caucasus, activates Iraq, places a factory in Iraq and the Caucasus as soon as possible. They also blitz Syria, and take Persia. After they land in the Caucasus and hold it for a turn, they fly planes over, then start threatening Stalingrad. Even if they don’t take it, it saps some recourses from Russia.
Hopefully this is enough information, but if it is not, just ask and I will do my best to supplement you. Thanks.
