The Belgian Army had approximately 200 combat vehicles at the time of the German invasion in May 1940. The vehicles were distributed among infantry and cavalry divisions for use as support weapons. The Belgian Army viewed their combat vehicles as defensive weapons. The practice of spreading out combat vehicles in so called "penny packets" (also used in the French Army at the same time) left them at a disadvantage against the German invaders, who concentrated their armour into organic units that could act on their own and that outnumbered the opposing vehicles even if units of the same type met. The Belgian Army had started to motorize its cavalry in 1936, spending 200 million Belgian Francs in the process. Tanks T15 light tank The T15 was a version of the British Carden Loyd tankette (Char Léger de Reconnaissance Vickers-Carden-Loyd Mod.1934 T.15). They had a two-man crew and were armed with a French 13.2 mm Hotchkiss machine gun in the turret. A total of 42 of these tanks were assigned to Belgian units. T13 (tank destroyer, models B1, B2 and B3) The T13 series was similar to the T15, with a main armament of a 47 mm anti-tank gun instead of a machine gun and of armour. They were regarded as tank destroyers and except the first model (B1) had rotating turrets. Total production for the T13: T13 B1, 35 produced as self-propelled guns, with a 47 mm gun at the rear behind a shield, with limited traverse. T13 B2, 21 produced. These started their life as unarmed Carden Loyd tankettes which were modified and equipped with a turret with a 47 mm gun in 1936. T13 B3, 150 produced, entered service in 1937 with a rotating turret and a revised suspension based on the Vickers Light Dragon Mark IIB. The Wehrmacht operated some captured T13s during the first years of the war, as the T13 had a more powerful main gun than the Panzer I and Panzer II, common German tanks in the early war years. There is a T13 B2 on display at Brussels Tank Museum. ACG-1 tank The Renault AMC 35 tank, known locally as the ACG-1, was armed with a 47 mm gun and a coaxial machine gun; 25 tanks were ordered, although only 10 were accepted into the Belgian army due to production delays. The Belgian ACG-1 and the AMC 35 had different turrets. Instead of
