On one end of the spectrum you have the elite tough as nails commandos and on the other end you have this guy. Arbuckle had never shot a gun in his life and he hoped he would never have to. Unfortunately for him it doesn't look like that's going to happen. Arbuckle is clumsy, slow to react, and practically scared of his shadow. He joined the military under pressure from his father and he hoped he would get a non-combat role like logistics or data analysis. Long story short, he didn't get it.
