The Marine Corps uses 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 FGM-148 Javelin and BGM-71 TOW are anti-tank guided missiles; both can utilize top-attack profiles to avoid heavy frontal armor and are heavy missiles effective past 2,000 meters that give infantry an offensive capability against armor.[2]

Marines with MARSOC, Force Reconnaissance, and MEU(SOC)s occasionally use specialized weapons that the rest of the fleet does not. In addition, some weapons are tested and evaluated in select units before acceptance and large-scale adoption. In a few cases, older weapons are brought out of retirement for limited use.
