I'll get my good old buddy Joshua ( Best mod ever btw ) to tell him to stop, if not Josh will demote him.
You are part of the U.S Army and in a convoy of Armoured Humvess driving through Afghanistan, suddenly, an RPG hits the Humvee you are in and it blasts the Humvee of the road and into the river next to the road. Everyone inside is dead, apart from you, you are in an Armoured Vehicle with armoured windows with metal grates on them, the doors are locked and you are sinking in the river, you have 4 minutes until you drown. All you have is small pieces of scrap metal, shrapnel from the RPG blast, a 9mm Beretta M9 pistol and a Combat Knife.
What do you do ?
