It ends with how to drive a truck. The encouraging part of the boot camp is that it shows off a lot of fun features. I didn't see any instances of air support. Choosing squads and specialists, and equipping an individual soldier. Typical Normandy missions include wading from the landing craft to take out shore defences, punching through bocage, ambushing enemy truck convoys, and waging house to house street fights with Panthers lurking in the debris.
Squads are, apparently for gameplay reasons, made up of five men, rather than ten or twelve.
You have eight squads to pick from, two of which are special weapons squads. You can move men between squads in the main squad screen. US forces do include some coloured troops. German forces do not include SS units. This is a very helpful feature.
