The AUBL/74 HVG is an experimental version of the Italian FIAT 6616 armored car armed with a 60mm HVG gun. The appearance of Soviet tanks, such as the T-54 and IS-3, which featured strong frontal armor, rendered most anti-tank guns from World War II obsolete. The development of HEAT rounds addressed this issue by enabling even light vehicles and infantry units to engage new post-war tanks. However, their low muzzle velocity made long-range fire inaccurate. In 1977, the Israeli company IMI and the Italian company OTO Melara began collaborating on a small-caliber gun capable of firing armor-piercing rounds at a very high muzzle velocity. This collaboration produced a 60mm gun called the HVMS (High Velocity Medium Support) in Israel and the HVGS (High Velocity Gun System) in Italy. It also produced a two-person T60/70 turret with an autoloader that could be mounted on various armored vehicles. OTO Melara built several prototypes with the new gun, installing it in an existing turret as in the AUBL/74 HVG and in a new turret as in the VCC-80/60. However, the 60 mm gun attracted little interest from potential buyers, so the Israeli and Italian companies continued development separately.

The AUBL/74 HVG was introduced as one of the rewards for the 2019 "Operation H.E.A.T." event. In terms of its characteristics, this vehicle fits well into the lineup of fast Italian machines. While the stabilized 60mm HVG gun offers good ballistics and armor penetration, the post-penetration effect of its APFSDS round is weak. Additionally, the rate of fire is low and the gun depression is inadequate. Additionally, the vehicle’s excellent mobility is thanks to its light armor and tightly packed crew layout.
