Alliance-9 (Chimera) How to complete?

TeriyakiTanker: They have really good passive light tanks, get yourself the Manticore or the T49 you have juice up the camo and the vision.  Make sure you have the commander vision system and sit in a bush until you get it done.  Do not fire just sit in a bush.  It will be map and team dependent to some extent but that is what you need to do.  Also put food on your tank and whatever bounty/bond equipment you have.  You can even dump a rammer until you get it finished and put on vents to help even more with cammo and vision.
