Infantry would be much more important in BS than LOMAC obviously.
In fact all Helicopter simulations I've played have had infantry (Apache, Hind Longbow2 Apache/Havok). Remember Hind? That had little guys running around that could use their weapons (guns, AT, AA) and would fight the enemy infantry/tanks/aircraft. I like how you could pick them up and then fly up to 5000ft, open the door and tip the Hind sideways and they all fell out :lol:
