The Stuart VI (5th CAD) (USA) is a premium gift American light tank. It was introduced as a premium pack in Update 1.70.1945 "Weapons of Victory". It was removed after the 2017 Victory Day sale and is no longer obtainable. It is essentially a gift version of the M5A1 Stuart with premium bonuses and a special livery.
With the fast reloading 37 mm cannon, the Stuart VI can deliver some good-hitting rounds if shooting at the flank at the enemies. A frontal engagement is possible but detrimental as Stuart's thin armour makes any incoming shot lethal. If coming up to heavily armoured vehicles like the KV-1, load the M51B1 APCBC round for maximum penetration. If a Stuart VI comes across a KV-1, the recommended course of action to take it out is to get in a point-blank range and fire at the turret ring or engine rear, otherwise, there is no way for the Stuart's 37 mm to penetrate the armour.
