The AMX-30 is a main battle tank designed by GIAT and first delivered to the French Army in 1966. The first five tanks were issued to the 501st Régiment de Chars de Combat (Tank Regiment) in August of that year. The production version of the AMX-30 weighed 36 metric tons (40 short tons), and sacrificed protection for increased mobility. The French believed that it would have required too much armour to protect against the latest anti-tank threats, thereby reducing the tank's maneuverability.
