  Stalwart Mk 1 load carrier
  FV622
  Stalwart Mk 2 load carrier. This had a two-man crew although a third seat could be fitted to the right of the driver as a field modification. It could also carry 38 fully equipped troops or the Gloster SARO bulk refueling pack as alternatives to the five tonnes of cargo. The jet drive units in all the Mk 2 variants were much more efficient, giving a claimed 9 knots.
  The most obvious visible difference between Mk 1 and Mk 2 variants is that the lower edges of the cab windows were now angled downwards rather than horizontal. This was to improve visibility at close-range, particularly when being marshalled by a banksman standing nearby.
  
  A total of 970 Mk 2 FV622, FV623 and FV624 Stalwarts were produced, of which the British Army purchased 946, with 24 sold to other countries.
  FV623
  Stalwart Mk 2 limber. An artillery ammunition supply vehicle for the Abbot self-propelled gun. There was an extra seat in the cab for the crane operator plus four rear-mounted seats for a seven-man crew. An Atlas 3001/66 hydraulic crane capable of lifting three tons was added to the cargo area to lift palletised loads of ammunition. The rear crew folding seats were separated from the main cargo area by a wooden divider, and protected from inclement weather by two folding PVC hoods on metal hoops.
  
  A total of 269 Mk 2 Stalwart limbers were produced.
  FV624
  Stalwart Mk 2 REME fitters' vehicle, based on the Mk 2 Stalwart. Two extra rear-mounted seats were added to the main cargo area for a four-man crew. An Atlas 3001 hydraulic crane capable of lifting three tons was added to the cargo area. This differed from that of the FV623 variant by having hydraulic anti-creep check valves fitted. This modified crane was more stable (and safer) for lifting and holding engine, transmission, and other heavy equipment whilst manoeuvring them into position.
  
  A total of 60 Mk 2 Stalwart fitters' vehicles were produced.
