Drake was startled when the man drove into the building. Instinctively he reached to his belt for his revolver, but it wasn't there. instead he grabbed his belt and put it on. there was a pouch on the belt where he took out a small needle with a little squeezable bulb on the end. He stuck the needle in himself and injected the little bit of fluid into his body, giving a surge of adrenaline. He picked up his incredibly heavy sword and shouldered it as he began walking toward the humvee. He kept his revolver in his left hand, aimed toward the turret in case the man decided to turn it toward him. Until then however he set about destroying the left side's tires as he rounded the vehicle.
"You may have an army, but that won't help you once your dead. Now, I see it like this, you have two options: Leave your gear behind and save your life," stayed at just the right angle to keep the gun from being able to aim at him, "or stay and get yourself killed."
The humvee would now have a tilt that would impair its ability to aim on the right side, making it open for anyone to move up on it. Should the corrupt soldier turn right, he could quickly attack the man in the turret, should the man keep his gun pointed left to pin Drake, well, he had a fun surprise fro that as well.
