A M41A4 Saber fires a simulated tube-launched, optically tracked, wire-guided anti-tank missile at a live-fire range aboard Marine Corps Base Camp Lejeune, North Carolina, Jan. 6. Wire-guided missiles are most commonly used in anti-tank maneuvers, where its ability to be used on targets within a limited line-of-sight range makes it useful for engagement.
