U.S. Special Forces

[Mustang]

There are a lot of commando raids and infantry assaults in the game. In fact, they probably make up most of the battles. Soldiers are also good for anti-tank because of the cost of modern MBTs (a 500 point Abrams can be killed by a 20 point infantry section). So they still have a big role to play. Also, special forces teams usually carry a lot more heavy stuff, like LMGs and satchel charges, than normal grunts, so they will do a lot of damage.
