To get free grenades, go to the mission The Last AA. as soon as the mission starts run over the box of grenades. DON'T refill your health no matter what. Just run over the box of grenades and it will give you an extra five grenades even if it says you already have the full amount of grenades. when it says to restart the mission, restart and repeat the above instructions. There is NO limit to the amount of grenades your can have.

To get a ton of xp and dogtags with limited weapons do "burning bunker" keep shooting with your own gun and don't use the machine gun alot. This will allow you to get frequent kill streaks. For each kill streak you can get many dogtags!
