The M4A4 Sherman VC Firefly is an up-gunned modification of the M4A4, which is the fifth variant of the early-generation Medium Tank M4 (Sherman) family. Armed with the powerful 76 mm Ordnance QF 17-pounder tank gun, this stopgap combination (before the introduction of the new generation of Allied tanks) was one of the most lethal tanks of its day, adding weight to the Allied battle to gain victory. Following Italy's rebuilding in 1945, some M4A4 Sherman VC Firefly variants were transferred to the country. In 1946, a minor military command was established for territory defence, and the unit received numerous other M4 Sherman variants. They served as the foundation for the first post-war tanker training school in Italy. In 1952, all M4 Sherman variants were officially decommissioned.

Introduced in Update "Starfighters", the M4A4 Sherman VC Firefly in the Italian Army ground forces is similar to the British counterpart, as they were provided by the British Army after World War II to aid in the reconstruction of Italy and the establishment of a territory defence force. The M4A4 Sherman VC Firefly, armed with the renowned 76 mm Ordnance QF 17-pounder tank gun, will provide players with the first significant boost in firepower compared to the early variants of the M4 Sherman within the Italian Army ground forces, which were mounted with the 75 mm M3 tank gun. The M4A4 Sherman VC Firefly will be the main backbone of Italian Army ground forces for a long time, thanks to the availability of armour-piercing discarding sabot (APDS) ammunition that will bring its firepower up to level with more advanced adversaries.
