13.5mm Heavy Autogun-4

Description

The 13.5mm Heavy Autogun is designed to provide heavy firepower against light armored vehicles and aircraft. It also provides a credible threat against personnel. It uses the same round as the Large Caliber Rifle-4.

 Too large to be readily man-portable, it is used mostly from fixed fortifications or mounted on vehicles.
