Which system is a fire-and-forget anti-tank missile with lock-on before launch and automatic self-guidance?

• A. FGM-148 Javelin
• B. M240B
• C. MK-19
• D. M27 IAR

Answer: (A)

The system being tested is defined by being a fire-and-forget anti-tank missile that can lock onto a target before launch and then guide itself to the target after firing. The FGM-148 Javelin fits this exactly: it uses an imaging infrared seeker that lets the operator lock onto the target before firing, and once launched it employs onboard guidance to steer the missile to the target without further input from the shooter. This autonomous guidance, along with its top-attack flight mode designed to defeat armored vehicles, is what makes Javelin the correct choice. The other items are not missiles with guided self-guidance; they are a machine gun, a grenade launcher, and an infantry rifle, none of which provide fire-and-forget anti-tank capability.
