Founded on June 14, 1775, the army is not only the largest branch of service in the U.S. military but one of the oldest as well (the Army National Guard is older – this component of the army was founded in December 1636.) Originally known as the Continental Army, it was established before the founding of the country, when most soldiers were equipped with muskets and swords. Now, almost 250 years later, the modern-day Army soldier has access to a range of small arms that play an important role in soldiers’ operational capabilities on the battlefield. These weapons are chosen on their ability to provide reliability, versatility, and firepower.
24/7 Wall St. referenced data from a range of sources, including military handbooks, government press releases, and firearms publications, including the Army’s Weapon Systems Handbook to identify every standard-issue gun in the U.S. Army. These guns were ranked on when they entered the service and included supplemental information regarding the type of firearm, range, caliber, and manufacturer from Military Factory.
The weapons on this list are used in a variety of operational capacities, ranging from pinning down enemy combatants to destroying vehicles and other assets. The list includes shotguns, side arms, machine guns, designated marksman rifles, sniper rifles, and more. (Also see, these are the 50 most popular guns of all time.)
The M4 carbine is one of the most common guns in the U.S. Army’s arsenal. The M4 is a lightweight, gas-operated, air-cooled, magazine-fed firearm that evolved from the M16. Due to its shorter barrel length, it offers soldiers increased maneuverability and adaptability in urban and close-quarters combat. The M4 is fairly modular and can be equipped with various attachments, including optics, laser sights, and under-barrel grenade launchers.
The U.S. Army employs the M240 machine gun for more specialized roles. This firearm is chambered for the 7.62x51mm NATO cartridge and serves as a medium machine gun. The M240 is designed for providing accurate and sustained fire, intended for suppressing enemy positions and engaging light armored vehicles.
These standard-issue small arms are being continuously improved, allowing U.S. Army soldiers to deal with a range of combat scenarios. However, it ultimately comes down to the soldiers’ training, not just equipment. Here are 21 bases where the U.S. military trains its combat forces.
