The Javelin missile is a portable, fire-and-forget anti-tank guided missile system. It is designed for use by infantry and can be launched from a shoulder-mounted platform or a vehicle. The missile uses infrared homing technology, allowing it to lock onto targets and guide itself to them after launch. Developed by Lockheed Martin and Raytheon, the Javelin is known for its high accuracy and effectiveness against armored vehicles. It has a range of approximately 2.5 miles (4 kilometers) and can be used in various combat situations, making it a valuable asset for modern military forces.
