A bank. Ive always wanted to do a bank. Like a full office type of bank. With counters and office cubicles and lots of hallways you see in movies. I'd have to use a MP5 for this. I hate using carbines in CQB. Oh and I'd use more flashbangs then necessary. On my MP5 I'd have a folding stock, the flashlight frontguard, a EOtech sight and double magazines. I wouldnt have a silencer cause I want the bad guys to know I'm coming for them with more equipment than required. And all the bad guys have got to have Ak's and wear bandannas.
This is how I'd look. or I could skip the guns entirely and look like this guy. Shanking people is fun.
