Trivia

 * The STG-44 is an assault rifle yet it's in the submachine gun category of the Gunsmith. This is because there is no room left in the assault rifles menu and is the closest thing to a submachine gun.
 * When leveling up, 1 kill = 1XP. So you need 250 kills to unlock Stock with the weapon you want Stock on.
