I would get shot a lot of times over and probably die first. I tend to be a great team player, if I live long enough...
In Combat Arms, I can do fairly well when it comes to killing people. I aim for the head, killing my enemies faster without having to get shot at much. I usually rush in, guns blazing, firing at the first person I see if I can kill them. My motto is: Don't shoot if you know you can't kill them. If you can't kill them, you shouldn't give your position away. Why try to kill somebody you know you can't kill? In teamwork games, I usually camp by the objective, relaying information as I see it and listening to teammates as things happen.
In COD, I just go in with my trusty-dusty Assault Rifles and destroy anything I see. I hate camping, it's not really that much fun and I don't think it has much significance. Who cares if you camp and get 25 kills in a row? It doesn't make you a better soldier/player. Maybe help win the game and seize the objective and THEN you'll be a "better soldier" in my eyes.
So yeah, I would probably get shot in the face in my first 10 minutes as a soldier... you can probably see my answer for this.
