I was on the side of nod and it was the old under map, a fleet of mammoths parked themselfs in front of the base and had engineers backing them up.
I watched our side try to blow them up from the comfort of the base and get no where, so I did the smart thing, I bought a sniper, went through the tunnels and came up behind the tanks.
I poked my head around the corner and saw a PIC sydney on the ridge on the other side of the map, she must have been typing a message cause she wasn't moving so I poped a cap in her head.
I looked towards the tanks and saw the engies reparing they were perfect targets so I blew their heads off as the were occupied.
Now the point of this story is that a whole lot of people were runing around in our base doing nothing, not even reparing so why didn't they use the tunnels as well and blow the tanks up from behind.
I sure there would be alot of confusion in the tanks if all of a sudden they were getting rockets and rail gun shots up their pie holes.
And yes we lost the game.
