Militaries that are not continuing to evolve their arsenals stand at a severe disadvantage to those that do. This has been proven throughout history with countries adopting new guns, vehicles, aircraft and the innovative strategies that come with each evolution. Embracing new technology on the battlefield is paramount to achieving victory. (Also see, the bombs and missiles used by the U.S. military.)
The U.S. military embodies this principle as it is perhaps the most technologically-advanced military on the planet. In part this is due to building on the weapons of the past and innovating further. Some of the weapons still used today have been in active service since World War II, and their newest iterations are just as deadly if not more. (Here are nine foreign made firearms used every day by the U.S. military.)
To determine the most recent small arms to enter U.S. military service, 24/7 Wall St. reviewed a range of sources, including military handbooks, government press releases, and firearms publications pertaining to small arms and light weapons currently used by the U.S. military. Small arms are ranked according to what year they entered the service, based on information from Military Factory, an online database of military vehicles, aircraft, arms and more used by militaries across the world. Data on the type of weapon, caliber, and maximum range also came from Military Factory.
The weapons on the list range from sniper rifles, shotguns, rocket launchers, and more. Some of the manufacturers are household names in gun culture, while others might not be as well known, but each plays a critical role in the success of the U.S. military.
