Welcome to today’s Photo of the Day! Here we have the gun that “replaced” the Bazooka. This is the Firestone M20 Recoilless Rifle (and the M18 version). At the start of World War II, just about every country had tanks that had thin armor and most countries were equipped with anti-tank solutions to deal with them. The United States was behind in this aspect for the entirety of the war. By the end of the War, the Germans had Tiger II tanks that were basically indestructible. In between the beginning and the end the US produced the Bazooka and Super bazooka but they quickly became obsolete despite their widespread usage. The solution was a gun that was portable but still fired a very large projectile. Recoilless technology was needed to achieve this. These guns use cartridges that have holes in them that vent the explosive gases forward and backward which effectively makes them recoilless. The M18 was the smaller shoulder-able version of the Firestone M20 Recoilless Rifle.
