This armored vehicle sports an anti-aircraft cannon
The M113 armored personnel carrier is one of the most versatile — and long-lasting — armored vehicles in the American inventory. The Army has just now, after 50 years of service, begun the process of replacing the M113 with the Armored Multi-Purpose Vehicle. Even then, the M113 will stick around in some capacity — over 80,000 have been produced.
One particularly notable variant of this APC is the M163. This is an M113 refitted with a turret-mounted M61 Vulcan 20mm Gatling gun. In one sense, this was a simple approach – the Army took the M61 Vulcan that has been a mainstay on fighters like the F-105 Thunderchief, F-104 Starfighter, and the F-4 Phantom and simply attached it to the M113. This gun proved to be quite a MiG-killer in air-to-air combat, and the assumption was it would be effective from the ground, too.
The M163 saw some combat trials during the Vietnam War, but the radar systems weren’t quite ready to take on targets in the sky. Like the M45 “Meat Chopper,” however, the M163 proved that ground targets were no problem for this anti-aircraft vehicle, especially when it carried over 2,000 rounds of ammo for the gun. The M163 soon found itself exported to South Korea, Thailand, Israel, and a number of other countries.
The M163 eventually received upgrades, giving it a better radar and making things simpler for the gunner. It also got more powerful rounds for the M61 gun. Yet, in American service, the M163 would be more known for its use as a ground-support asset. However, the Israelis did score three kills with the vehicle, one of them a MiG-21, during the 1982 Lebanon War.
After Desert Storm, the Army retired the M163, replacing it and the M72 Chaparral with the 1-2 combination of the M1097 Avenger and the M6 Bradley Linebacker air-defense vehicle.
