They both go "bang".
Guns are only able to hold a certain amount of ammunition. Once one has fired the gun one bullet has left the chamber. Once all of the ammunition is gone, one will need to reload the gun in order to fire off more ammunition. If ammunition is not reloaded, then the gun will make a noise, but nothing will happen.
soldiers always carry ammunition for reload their gun.
