Nice tacts, just stay up there and hope they don't see you. Your handgun is also way more accurate then your rifle so you don't warn them. I'll have to try that one time My tactic is just to feed batteries and repairs to the MAXes and throw some proximity mines at hardpoints. The moment they manage to kill you and overrun your position, you get a lot of kills and vengeance bonuses @ Zeo, depends on your timezone :P
