Without this key piece of military hardware, you are done for as a tank loader. Some might even say Rircardo’d.Sorry I was just having fun lol.Main Battle Tanks need gun ammunition like all other weapons of war. The tank is only as good as the loader that is providing the firepower. The main guns of most modern day tanks require the shells to be loaded either manually by a tank crewman or automatically by a tank auto-loader. The autoloader has flaws as does any tank soldier. And example being the T-90 and the M1A2 Abrams, the vehicles have their own way of fighting on the battlefield.
