The Strv 101 was the Swedish designation for the Centurion Mk 10. In 1959-1960, Sweden acquired another 110 of Centurion tanks from the United Kingdom, this time the improved Mk 10 to reinforce the existing fleet of Strv 81s. The Strv 101 were a fitting choice since the older 84 mm cannon were getting obsolete in usage and the older version Strv 81 would be getting upgrades to meet the standards of the new Strv 101 which meant they would get a 105 mm L7 among other things, but these wouldn't happen till 1964-1966. The Strv 101 would only get a upgrade once and would serve in the Swedish army until 1995 when they were phased out for the Strv 121. It had a long service alongside the Strv 103 as the backbone for the armoured forces of Sweden, playing a vital role in Swedish defence. Their fate is either dismantled or ended up in museum at the end of their almost 50 year service.

Introduced in Update 1.97 "Viking Fury", the Strv 101 has increased firepower over earlier Strv 81. As one of the first tanks to be equipped with the 105 mm Royal Ordnance L7A1 tank gun, it equips players with devastating firepower that will undoubtedly destroy any opponent's tanks. Ammunition options are limited to armour-piercing discarding sabot (APDS) or high explosive squash head (HESH) rounds. Nonetheless, with a staggering 350 mm of armour penetration for the primary anti-tank ammunition, the Centurion Mk 10 is capable of dealing with any foe on the battlefield. However, the mobility of all Centurions is below average, owing to the tank's enormous weight combined with a low horsepower engine. The playstyles are quite similar to the Strv 81, with nearly identical armour arrangement.
