Hello Ian
When I escaped the clutches of HM service, individual unit / vehicle markings were not common. Certainly no arm of service and divisional signs as were the norm in the 70's.
They had been virtually discontinued in the mid-eighties. The only exceptions being the union flag front and rear, and sometimes the squadron/company symbols displayed on the side. (Triangle for A Coy, Square for B Coy, Circle for C Coy etc).
I don't recall any Wolf Rovers bearing any markings, except RAD HAZ markings near antenna mounts.
Hope this helps.
