You have to understand that even though you are only the communications guy and have far less actual combat experience than your teammates, for some reason normal world physics don't seem to apply to you. In fact, you don't even seem to be in control of your own actions. Instead, it feels like you are in a game, with crappy graphics but awesome gameplay, and someone is controlling you. I just hope that person knows what he/she is doing, for your sake.
