The Leman Russ is crewed by a minimum of four crewmen, including a commander, gunner, loader and driver. The Leman Russ can perform to its optimum capabilities when all of these elements are combined during an Imperial armoured advance. This characteristic does make the Leman Russ vulnerable to assault from these angles, requiring infantry support, other tanks or very careful operation to protect the vehicle. Its side and rear armour remain thinner to reduce the strain on the tank's engines. Though slow, its frontal armour is strong enough to withstand the multitude of weaponry wielded by the enemies of the Emperor of Mankind. It can survive the worst the galaxy can throw at it, and can run on almost any liquid fuel. Far from a sophisticated vehicle, the Leman Russ was designed and built with reliability and versatility in mind.
The tank is named after the Space Wolves Primarch, Leman Russ. The Leman Russ is the main battle tank of the Imperial Guard, and is also the most widely deployed tank in the Imperium. Look at some interesting conversions, painting and just interesting examples of this model. You can't speak about Warhammer most popular models without mentioning Leman Russ.
