AP2782 - Group 7

BC = Bogie Centres. GC = Ground Clearance. MPG = Miles per gallon. TC = Turning Circle. WB = Wheelbase.

RAF (Stores) Ref Nos were not given in this document but where they are shown, they have been assumed from later versions of AP2782. This edition also did not include photos so these have been added from AP2782A. When a vehicle appears in more than one edition of AP2782, the technical details have been assembled from all available data.
