Stridsvagn 122 (Battle Tank 122) is a modified version of the German-built Leopard 2A5, utilizing newer technology such as, command, control and fire control systems, as well as reinforced armor and long-term combat capacity. Externally, the vehicle can be distinguished from the Leopard 2A5 by the French GALIX smoke dispensers, different storage bins, and the thicker crew hatches.[1] The Strv 122B, a variant equipped with modular AMAP composite armour from IBD Deisenroth, provides "360° protection" against threats such as EFPs, RPGs and IEDs.[2] The width of exactly 4 metres (13 ft) has been kept, while the weight increases by only 350 kilograms (770 lb).[2] Discovery Channel named it the best main battle tank in existence as of 2010.[3]

Features[]

The Stridsvagn 122 was designed to fight in Swedish conditions including heavily forested areas as well as urban terrain. It also had to overcome the perceived flaws of the original German tank, and features the following abilities:[4]

Heavily reinforced armor to protect against man-portable anti-tank weapons. An advanced CBRN defense system for protection against chemical, biological and radioactive weapons. Amphibious ability to pass through water up to 1.4 m deep. Quick ability to discover, identify and lock on a target with the assistance of a laser rangefinder, infrared sights, and a speed/distance/accuracy calculator for maximum accuracy. Ability to fight an opponent effectively at a distance of 4,000 meters whilst maintaining a maximum combat range of 8,000 meters. Ability to lock onto numerous targets at once, enabling the tank to fight numerous enemy vehicles without having to manually re-aim the gun after every shot. Active communication for improved cooperation between units.

Production and Service[]

As of 2013, only 120 of these tanks remain in active service while 160 earlier versions are kept in storage as a part of the Swedish army reserves. The active tanks are divided upon three regiments, namely Skaraborgs regemente, södra skånska regementet, and Norrbottens regemente.
