MGM-166 LOSAT
The MGM-166 LOSAT (Line-of-Sight Anti-Tank) was a United States anti-tank missile system developed in the 1990s by Lockheed Martin (originally Vought), to defeat tanks and other individual targets. Instead of using a high explosive anti-tank (HEAT) warhead like other anti-tank missiles, LOSAT employed a solid steel kinetic energy penetrator (KEM) to punch through armor.
