To be fair to the RRF DS, the name might be the same ( JNCO's Cadre ) but there appears to be a world of difference in the content, between Corps and Infantry JNCO's Cadres.
For sure, but much was. One exercise the Workshop (7 Armd) had moved into some farm. One evening a couple of young infantry types turn turn up with a 432 that needed fixing so they stayed with us for a while. We took them to the cookhouse for rather nice evening meal, three courses all laid on in a nice warm tent after which we went back to the well heated (this was in a BAOR Winter) ERV for a coffee/beer, game of cards etc.
We explained this was how it was for REME Workshops but that we did venture outside for stand-to at sunup and sundown though there was not much else for Techs to go outside for. They were quite amazed by this all and we wondered if when they got back to unit they got busy trying to transfer.
