The FGM-148 Javelin is an American-made, man-portable third generation Anti-Tank Guided Missile (ATGM) launcher manufactured by Raytheon and Lockheed Martin.
The Javelin was designed to replace the aging M47 Dragon anti-tank missile, previously used by the United States during 1975 - 1995.
In real life, the Javelin's missile is capable of penetrating a main battle tank's base and explosive reactive armor. It does this by utilizing two shaped-charge warheads in tandem. The smaller warhead detonates the explosive reactive armor allowing the larger warhead to penetrate the tank's base armor. It is used by the Alliance of Nations during the War
