or one Challenger power pack. 105 of these were produced. FV513 Mechanised Recovery Vehicle (Repair). Also operated by REME detachments in Armoured Infantry battalions. It is equipped with a 20-tonne winch and 6.5-tonne crane plus power tools and (like the FV512) is able to tow a trailer carrying two Warrior power packs or one Challenger power pack. 39 of these were produced. FV514 Mechanised Artillery Observation Vehicle. This is operated by the Royal Artillery as an Artillery Observation Post Vehicle (OPV) and is fitted with mast-mounted Man-packable Surveillance and Target Acquisition Radar (MSTAR) and Position and Azimuth Determining System (PADS), with image intensifying and infra-red equipment. The only armament is the 7.62 mm machine gun, as the 30 mm RARDEN cannon is replaced by a dummy weapon. This allows space for the targeting and surveillance equipment while still keeping largely the same outward appearance of a standard Warrior in order to avoid becoming a priority target. 52 of these were produced. FV515 Battery Command Vehicle. This is operated by the Royal Artillery. 19 of these were produced. Desert Warrior. This was an export version adapted for operations in hostile desert conditions. It was fitted with the Delco turret as used on the LAV-25 wheeled IFV, mounting a stabilised 25 mm M242 Bushmaster chain gun with coaxial 7.62 mm chain gun and two Hughes TOW ATGM launchers (one mounted on each side). In 1993, Kuwait purchased 254 Desert Warrior vehicles. Warrior 2000. This was a new version developed for the Swiss Army. It did not enter production. It featured an all-welded aluminium hull, increased armour, digital fire control system and more powerful engine. It was fitted with the Delco turret, or a Land Systems Hagglunds E30 turret with Alliant Techsystems 30 mm Bushmaster II Mk 44 cannon. Armoured Ambulance. Six Warriors, with armaments removed, were converted to armoured ambulances for use in Afghanistan during Operation Herrick. VERDI-2 (Vehicle Electronics Research Defence Initiative) was a technology demonstrator built on the hull of an FV510 in 1993. It utilized the 40mm CTAI cannon, in addition to eight Starstreak missiles in two quad launchers, as well as the ADAD system later seen on the Stormer HVM. It did not enter production. Optionally-Crewed Warrior. In late 2018, an optionally-crewed variant of the vehicle was demonstrated as part of the British Army's Army Warfighting Experiment 2018 'Autonomous Warrior'. This was delivered by British Engineering firm Digital
