Call of Duty 2: Big Red One

Machine guns:
When manning a machine gun, a short six or seven round burst works best against enemies. If a lot of enemies get close, lie prone and throw a grenade at them. Then, quickly get back on the machine gun.

Bomber mission:
In the bomber mission, at the end it will allow you to choose any machine gun turret to defend the plane from. It is recommended, at least under the hard difficulty setting, that you stay at the back turret. It takes too long to get to the front, and your plane may get shot down.

Last mission
When you are going thought the dragons teeth, take out the machine gunner and his friend in the middle tower. Then, make a run half way thought the dragons teeth. Next, go prone behind a tooth. Take out the enemies around you and in the tower. Then, get up and run all the way through and underneath the last tower for cover. Wait for your squad to arrive, then storm up the hill and go into the bunker.

Counterattack mission
When Brooklyn says "Finally, this crappy mud pit is ours!", just start running away from where you came. Equip a BAR or another MG while running. You will not have to worry about the tank dealing damage and can concentrate about the Nazis on your way.
