The GBT 155 is a British turreted artillery system developed by Vickers Shipbuilding and Engineering Limited (VSEL) in the early 1980s as a modular, self-contained turret for mounting on existing tank chassis for export and the domestic market. This SP is built upon the Vickers Mk 3 MBT chassis, which is very similar to Vickers Mk.1 tank, already presented in the game.

This vehicle is very exposed to enemy fire, but has a decent mobility - It features 720 HP, 2,500 RPM and can reach a top speed of 50 km/h. The GBT 155 is armed with a 155 mm FH70 cannon, able to fire the NATO standard HE, Smoke, and HE-VT shells. Additionally, the GBT 155 is equipped with smoke grenades.
