The FGM-148 Javelin features include which of the following?

• A. Fire-and-forget with lock-on before launch, and an automatic self-guidance
• B. Requires continuous operator guidance
• C. Has only a top-attack mode
• D. Cannot engage buildings or helicopters

Answer: (A)

The main idea this question tests is how the Javelin guides and uses its missiles after launch. The best answer captures its fire-and-forget nature with a lock-on before launch and autonomous guidance once fired. You lock onto the target with the infrared seeker, then launch; after that, the missile steers itself to the target without the operator needing to steer it further. This capability frees the shooter to take cover or maneuver, which is a hallmark of fire-and-forget systems. The other statements conflict with how Javelin actually operates: it does not require continuous operator guidance, it isn’t limited to a single attack mode, and ignoring its ability to engage a range of targets (including armored threats and potentially other suitable targets) would overlook its versatile guidance and flight profiles.
