A very few words explain much of what happened in the early 90s onward. "Garrison Sergeant Major - RSM 15 Signal Regiment". The Regiment was the single most purposeless military organisation ever set up. It controlled fuck all, had two squadrons theoretically under command and had influence over three more, but there were a lovely big CO's slot, an Adjutant's slot and room for an RSM, so that was just doozy.The Chunkies used to do guard dog patrols in Lisburn in 73-76 time with Alsation dogs. The joke was that the only reason the dogs had a Chunkie handler was because the dogs couldn't answer the phone. Things were pretty relaxed then with no one bothering to much with haircuts and the usual army f*ckwittery. You can tell when peace is returning as the 'Great God Bullshit' and all his disciples come out of the woodwork and spread his gospel.
Making RSM 15 Sig Regt the Garrison RSM and giving him the whole Thiepval trainset, theoretically, to play with, was a recipe for silliness.
