What Assault Rifle Does the USMC Use?
The United States Marine Corps (USMC) has been a prominent fighting force in the world since its inception in 1775. Throughout its long history, the USMC has relied on various assault rifles to equip its members. In this article, we will explore the type of assault rifle used by the USMC and answer the question that has piqued the interest of many: What assault rifle does the USMC use?
The M27 Infantry Automatic Rifle
The USMC has issued the M27 Infantry Automatic Rifle (IAR) as its primary assault rifle. The M27 IAR is a 5.56mm, select-fire assault rifle based on the HK416 by Heckler & Koch. Designed to be used by both infantry riflemen and automatic riflemen, the M27 IAR is a versatile and reliable firearm that has become an integral part of the Marine Corps’ arsenal.
Replacing the M249
In 2011, the USMC commandant ordered the M27 IAR to replace the M249 Squad Automatic Weapon (SAW). The M27 IAR’s lighter and more compact design made it a more suitable choice for the Marines, who found it easier to maneuver with the new rifle. This decision was made to cater to the changing nature of warfare, where weight and mobility are increasingly important factors.
