Brute shot noob combo, plus giving a Fuel Rod Gun to an A.I. character

Works amazingly well...*zapp* BAM *, down they go.  Helped me wreck a Brute Prowler without having to use a rocket!  Then, right before the section where you clear out the final LZ for the frigate, I was on a Mongoose with a marine wielding the FRG, hopped off and used my rockets to kill the standard Wraith in the valley,  exchanged the RL for a plasma pistol, then backtracked for an undamaged chopper and destroyed the first AA Wraith.  Get this--another A.I. marine drove the Mongoose, and he and the FRG wielder killed several Brutes and the second AA Wraith for me!  I try not to let them drive, though...they like driving right into a nest of enemies--then stopping dead, guaranteeing your explosive demise!
