Sometimes it’s the most obvious of circumstances that can cause us difficulties and in this case that is exactly what happened. As this Army Private was shooting his rifle during a training mission, the gun stopped firing. The Private’s Sergeant asked him if he knew why the gun was not firing. The Private in question had no clue. As the Sergeant removed the ammo clip from the rifle, he pointed out to the Private that the cartridge was empty therefore the gun will not fire if there are no bullets to be fired. As this was taking place you can hear the Sergeant laughing out loud as he watched the dumbfounded look upon his recruits face.
