As of 2013, the typical infantry rifleman carries $14,000 worth of gear (excluding night-vision goggles), compared to $2,500 a decade earlier. The number of pieces of equipment (everything from radios to trucks) in a typical infantry battalion has also increased, from 3,400 pieces of gear in 2001 to 8,500 in 2013.
The basic infantry weapon of the Marine Corps has been M16A4 service rifle. Most non-infantry Marines have been equipped with the M4 Carbine or Colt 9mm SMG. The standard side arm is the M9A1 pistol. The Colt M1911 is also being put back into service as the M45A1 Close Quarter Battle Pistol (CQBP) in small numbers. Suppressive fire is provided by the M27 IAR, M249 SAW, and M240 machine guns, at the squad and company levels respectively. In 2018, the M27 IAR was selected to be the standard issue rifle for the all infantry squads. In 2021, the Marine Corps committed to fielding suppressors to all its infantry units, making it the first branch of the U.S. military to adopt them for widespread use.
Indirect fire is provided by the M203 grenade launcher and the M32 grenade launcher in fireteams, M224 60 mm mortar in companies, and M252 81 mm mortar in battalions. The M2 .50 caliber heavy machine gun and MK19 automatic grenade launcher (40 mm) are available for use by dismounted infantry, though they are more commonly vehicle-mounted. Precision firepower is provided by the M40 series and the Barrett M107, while designated marksmen use the DMR (being replaced by the M39 EMR), and the SAM-R.
The Marine Corps utilizes a variety of direct-fire rockets and missiles to provide infantry with an offensive and defensive anti-armor capability. The SMAW and AT4 are unguided rockets that can destroy armor and fixed defenses (e.g., bunkers) at ranges up to 500 meters. The smaller and lighter M72 LAW can destroy targets at ranges up to 200 meters. The Predator SRAW, FGM-148 Javelin and BGM-71 TOW are anti-tank guided missiles. The Javelin can utilize top-attack profiles to avoid heavy frontal armor. The Predator is a short-range fire-and-forget weapon; the Javelin and TOW are heavier missiles effective past 2,000 meters that give infantry an offensive capability against armor.
