OK the achievement "cut the blue wire...no the red wire!" is to disarm 25 bombs in IoC. This can take a while but if you stand in this spot you can get in it one battle. Once the battle starts the front gate will open. stand right in the middle of where is should be, once it closes youll be stuck inside it. well not suck. from there you can disarm bombs the other faction puts on the gate. and to make it better no one can target you or know you are there.
