Hours of experimentation later, I decide to make the jump to multiplayer. Moments later another assault wave begins, all of my men run out of ammo, and everyone dies.
At that moment, I learn that soldiers can run out of ammo and that every soldier in the game has his own inventory system full of grenades, bandages, and entrenching equipment. They've held off a counterattack, and I see one soldier has a red ammo clip over his head. My Marines are having a hell of a time taking this unnamed island back from the Japanese-even with my assistance in the form of a dead-shot sniper squad leader in Direct Control mode. Self-education takes time, so at this early stage I'm incompetent.
