well for the missions a couple of good ideas would be Hamburger hill,
it would be easy to create as all you need is choppers, men, M2's and a few fortressess.
brief outline: 4 squads are transported by chopper to the base of the hill,
where the men will assault the hill in seperate squads.
all up the hill will be heaps and heaps of men and a large number of machineguns.
at the top there is a few fortresses to be couqured.
once u couqured them a couple more choppers will reinforce your position, to await a fierce counter attack.
fend them off and ui win the stage. easy.
