The FGM-148 Javelin is a man-portable fire-and-forget anti-tank missile designed to destroy enemy heavy armor. Its automatic infrared guidance system allows the operator to fire from a safe distance and seek cover while the missile is en-route to it’s target. When the weapon functions properly it provides a safe way for ground troops to neutralize enemy tanks. When it doesn’t function properly, well, we’re about to find out what happens when it doesn’t function properly.
The video below shows what happens when the Javelin’s propulsion system malfunctions. The Javelin utilizes a soft launch mechanism that allows a soldier to launch the missile with minimal recoil. In a soft launch a launch motor propels the rocket out of the tube but extinguishes itself before clearing the tube, this prevents the operator from being burned by back blast. When the missile is a safe distance from the operator a second flight motor is ignited which delivers the missile to the target.
This video below shows what happens when the second flight motor fails to ignite and the soldiers are forced to sprint for safety.
