Here's what I see when I watch FPS games like this.
Pick a soldier. Any soldier will do because you're a private and you suck.
Look around on world map. No idea where the enemy is.
Run after a fellow soldier on the premise he must know where he's going. He doesn't.
Run, run. Run. Catch up to fellow soldier and others. They are shooting. No idea at what.
Run, run and get behind cover. Peek over and see smoke in the distance. Fellow soldiers are shooting at smoke so you do to.
Do nothing for 20 seconds while reloading.
Look over cover again. Everybody but you has moved forward so run, run. Run.
Catch up and shoot at smoke again.
Reload. Look around at fellow soldiers shooting at distant smoke.
Look over cover and shoot at smoke.
Get shot twice. Die.
