Abbreviation meaning Regimental Police. The RSM`s henchmen. Usually suffering from SMS (Small man syndrome) they insist on walking instep even when out with the wife and kids. The keepers of camp discipline and the keys to the wheel clamps!
Usually found lurking around the guard room with their Lance Corporal tape flagged by big fuk off R and P either side, made of brasso that some sus has to clean daily. Also known to carry a shitty version of a pace stick.
