Used by the Germans in WWII, the Pak 40 makes other anti-tank guns look like toys. It can fire 10 shots per minute, and the force of one shot can blast through half a foot of steel. Watch as host Paul Shull fires one in the empty desert. 🎥The Weapon Hunter | Smithsonian Channel Aviation Nation

The AC-130 is the world's biggest flying artillery gunship - nicknamed 'Hell in the Sky.' With three side-firing weapons, a 25mm gatling gun, a 40mm Bofors cannon, and a 105mm howitzer, it's easy to see why it got its name. 🎥Air Warriors | Smithsonian Channel Aviation Nation

Tank shells are stored in armored compartments. Depending on the tank, a crew member or an autoloader selects and loads the shell into the gun’s breech. Manual loading involves physically inserting the shell, while autoloaders do this mechanically. Once loaded, the tank is ready to fire. #didyouknow #history #army #reels #facts | Inside History
