The Pvrbv 551 was a tank destroyer built by Hägglunds & Söner in Örnsköldsvik, based on the retired Ikv 102 / 103 chassis, which were phased out by the Ikv 91. Stemming from the UDES 33 prototype, the Pvrbv 551 was upgraded, adopting an elevator mechanism for the Rbs 55 ATGM launcher. This innovation allowed deployment and subsequent protection within the chassis through a top-mounted two-door hatch. The Rbs 55, Swedish designation for the BGM-71 TOW, offered a commendable range of 65 to 3000 m, enhancing the vehicle's agility as a TOW system carrier. Despite increased mobility, the integration of a Ford V6 engine, shared with the Bv 206, compromised off-road capabilities compared to the original engine. Between 1984 and 1986, 57 Pvrbv 551 units were manufactured and distributed, finding placement in Armoured and Mechanized brigades as support vehicles. Serving in the Swedish Army until the early 2000s, the Pvrbv 551 earned praise for its economical and prompt deployment, effectively fulfilling critical operational requirements.

Introduced in Update 1.97 "Viking Fury", the pvrbv 551 is a small anti-tank guided missile (ATGM) tank destroyer used by the Swedish Army's ground units. It is equipped with the well-known BGM-71 TOW and can engage a wide spectrum of adversaries. It is critical that players use ambush tactics and limit their exposure to the enemy's line of sight during battles. The vehicle's survivability is entirely focused on rifle-calibre fire. The chassis is enclosed by armour plates ranging in thickness from 5 to 25 mm, with the front providing some protection against light machine-gun rounds. Players should try to reposition frequently since even close explosions of artillery shells can severely damage, if not destroy, the vehicle.
