Commando Archive

I know that in these times of Jedi, holocrons, 2.5x modifiers, broken HAR's and messed up skill lines this question may seem irrelevant, but i've h eard that commandoes are needed to change somethign in fation bases in order to win a base form the opposing base. Can someone explain this ability to me and let me now how to do it? THanks

Oberon.. Commando till i drop 3443, despite the 2.5 (playing dead wrks 4 me!)
