Robocop. (Enforcer, we all need the big guy.)
Snake eyes. (Assasination and intelligence gathering.)
Samus, Master Chief, and YES Jet from fracture (as my main assault force.)
I'd be the leader who sits on his ass and gives them orders through a headset.
Think of it I send in the Main assault force to distract the guards as Snake eyes sneaks in and get what we need, once confirmation from Snake eyes is reached we send in Robocop as a bulletsponge, once the assault force pulls out Robocop will declare,"THANK YOU FOR YOUR COOPERATION." And Vishoo clunk vishoo clunk vishoo clunk out of there.
