.. and maybe not as clear cut as other AH rules?
Okay, that made me chuckle. No doubt about it, it's a complex game with a lot of rules vagaries.
At the end of the rule book is a sequence of play. I'd have that out at all times...in fact I still do when playing. There simply is no one easy way to play this game but coming here is a great way to get answers.
1) All movement is done in one step...well two: naval movement with all its possible interception. And then air and ground units.
2)Then combat is done at the attacker's discretion: either doing his attrition then his offensive, or the other way around but offensives are done universally. That is if you are conducting an offensive on two fronts all that action occurs simultaneously; you don't do the offensive in the west, then the one in the east. You can do two attritions separately divided by the offensive.
3) Not much difference; the rule book was polished and the map buffed up. There are many rules clarified over the years in The General magazine. There is a file here: http://www.boardgamegeek.com/filepage/55571/3r-45-rulebook-d... with the questions and answers inserted at the appropriate rule point.
Finding some kind soul with the time to play a game with you on Vassal might be the best way to get started.
