Stacking:

Use this to open doors when you don't know what
may be lurking behind them. Make sure you pick 
the lock or use a key on the door first if you 
have to. Lay one guy down, and move him right 
up to the door. Put another guy in the kneeling
position, and move him behind the guy laying 
down. Stand a guy up and move him behind the 
guy kneeling down. Now you have three guys 
ready to fire through the doorway once you open
it. Put everybody on "agressive" mode, your guns
on burst, and use the guy laying down to open 
the door. Anything in the immediate line of 
sight turns into a bloody mess. Raider bosses 
die quick this way.
