What does FADM mean in UNCLASSIFIED

A Field Air Defence Mount (FADM) is typically a vehicle-mounted surface-to-air missile system used to defend against attacks from aircraft and other airborne threats. It usually consists of radar systems and launchers mounted on armoured or lightly armoured vehicles, such as armored personnel carriers or trucks.

The FADM operates in much the same way as any anti-aircraft weapon system. When an airborne threat is detected by the radar system, the FADM's tracking systems lock onto it and launch missiles at it. The missiles are guided by a sophisticated computerized fire control system that can track multiple targets simultaneously.

The primary benefit of using a field air defence mount is its mobility. FADMs can be quickly deployed in theatre and when necessary quickly relocated to provide cover for different areas. This makes them invaluable in providing air defence cover during operations where there may be limited infrastructure or personnel available to man fixed sites such as air bases or anti-aircraft artillery batteries.

Depending on the type of FADM, different types of missiles can be used. Some common options include heat seeking air defense missiles like Sidewinders, longer range radar guided missiles like Patriot Missiles, surface to air interceptor missiles like Sparrows, or cruise missiles like Tomahawks.

Generally speaking, air defense is operated by dedicated personnel from specially trained teams known as 'Air Defence Troops'. These troops are responsible for operating the systems and ensuring their proper function at all times. Additionally, many militaries also employ dedicated mechanics who are responsible for maintaining the weapons systems in good shape and making sure they are always ready when needed.
