The U.S. Army primarily uses the M4 carbine, a lightweight, gas-operated, air-cooled, magazine-fed assault rifle. It fires 5.56x45mm NATO cartridges and is known for its versatility, accuracy, and adaptability with various attachments. The M16 rifle is also still in use, particularly for certain units. Additionally, specialized units may utilize other rifles, such as the M14 or various sniper systems.
