As far as fascinating gear goes, bayonets gotta be near the top. Americans fought the British armed with rifles and bayonets. Ever since then, the United States military has fielded bayonets in some fashion or another. Bayonet charges were quite common when your rifle’s fire rate was two rounds per minute and cavalry on horseback could rout a troop.
These rifle-mounted blades in battle were quite common up to the end of Korea. Millet’s charge in Korea is one of the most famous. Marines wielding bayonets charged across an open field to take an airfield on Peleliu during World War 2. Heck, Vietnam saw some bayo use, but around that time, the bayonet had begun to see its decline. To do this day, various rifle-mounted knives remain issued to troops, and they’ve even been used a time or two during the Global War on Terror.
