The tanks were placed in Cavalry Divisions and regiments fielded as many as six of the vehicles. The T.15 marked a Model 1934 offshoot developed for the Belgian Army. The turret, weapons and radio gear could, again, be completed to customer requirements. The following year, the Model 1934 was introduced and this was differentiated by its revised suspension system (helical springs). Armor protection reached 9mm in thickness. Overall weight was 3.8 tons and the operating crew numbered two - driver and commander/gunner. The tank could hope to make 42 kmh on prepared surfaces. With the leaf spring suspension system, the vehicle held some cross-country value. Drive power was from a Meadows ESTB 6-cylinder liquid-cooled gasoline engine of 90 horsepower coupled to a five-speed transmission system. A Vickers 7.7mm machine gun was the standard armament fit but the customer could also install local guns of similar size and function as needed. The turret could be completed with faceted sides or smooth (cylindrical) depending on customer requirements. The initial production form was the Model 1933 which showcased a riveted hull and turret. Vickers-Armstrong developed its 'Commercial Light Tank' specifically for export sales and the series must of proved quite lucrative for the company during the pre-war period. This opened the door for established tank makers, like those in Britain (Vickers), to hock their wares to a whole new breed of customer. After the cessation of hostilities, a rebuilding Europe saw many powers clamor to acquire inexpensive, light-class tank systems for their own defense.

World War 1 (1914-1918) brought to the forefront the need for tanks in any modern army inventory.
