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.[3] 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.[4] The width of exactly 4 metres (13 ft) has been kept, while the weight increases by only 350 kilograms (770 lb).[4]

Features[edit]

The Stridsvagn 122 was designed to fight in Swedish conditions including heavily forested areas as well as urban terrain.[citation needed] It also had to overcome the perceived flaws of the original German tank, and features the following abilities:[5]

  • Heavily reinforced armor to protect against man-portable anti-tank weapons.
  • An advanced CBRN defense system for protection against chemical, biological and radioactive weapons.
  • Wading capability 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 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[edit]

As of 2013, 120 of these tanks remain in active service. Most of the 160 Leopard 2 A4s (local designation Strv 121) that were originally leased are being returned to Germany.[6] The active tanks are divided between three regiments, namely Skaraborgs regemente, södra skånska regementet, and Norrbottens regemente.
