Alliance warfare comes in may forms. There is no "set" war strategy. It depends on a myrad
of variables, such as Total NW, Avg NW, participation (moral), allies, etc. I'll try and show
these case by case.
#1) - An alliance with a lot of members, and a low avg NW.
This is the easiest form of war, the GS kill. You stock up on troops, and merely kill off their
countries with losts of Geurrilla attacks. Make sure you have it so that it's not big guys doing
attacks at the end to finish him off. What's best is when you have it going from top down
where the big guys start off with attacks, killing off his military, and it moves down your
chain so that everyone gets some shots in. This type of warfare takes the least amount
of thinking.

#2) - An alliance with a lot of members and a high avg NW.
In this case, you'll probably want to start out with either some AB's or BR's, and then switch
into farming mode, where most of your attacks are SS's. Make sure when you do your
AB's/BR's you spread out the hurt, rather then concentrating on one target. Do the same
for your SS's. Don't send more then a max of 1/2 your military, and aim to send only 1/3.
Your goal isn't to KILL off countries, merely wound alot of them.

#3) - An alliance with fewer members and high avg NW.
This is alot like #2, however, depending on who you're fighting you won't actually switch to
a farming stage. You'll just go for AB's / BR's the whole war. As with #2 try and keep the
smack down delivered to as many targets as possible, so that you aren't hit with deminishing
returns.

#4) - Small alliance, low avg NW : Go for GS kills. Basically exactly like #1, cept you're not going to win :)
