MRD's
By the '80s MRD's were operated by ATechP's (snco's IIRC) and the refueler by an MTD suitably x annotated and MRD trained.
At Gut. in the early '80's snow clearing was so often f****d up due to the duty snow clearing officers lack of experience. OC MT Sqn got OC Eng to agree that only the 4 officers and 3 warrant officers of the MT Sqn would cover this duty, of course mistakes were still made, (that b****y wind changed, again) but for instance, they were not afraid take preemtive action to prevent surfaces icing up, (the local stadt had to be informed of qtys of chemicals deployed due to the high water table) and of course they understood the capabilities of the kit.
BTW anyone remember those ice "cowpats" that used to appear thru the friction course
