Hello all, can anybody help with, or suggest where to go, for help deciphering RE trade qualifications. I'm an ex sapper myself but even i am having a bit of difficulty with some of them. They are primarily plant operator trades, i know what some are but would like to clarify the fine detail. I'll list them below; AQ. Pnr. RE D3. - listed as specialist qualification. I know what a Pioneer is and where it fits into things but what is 'AQ' ? Operator excavator B2 & D3 - i'm familiar with OP Ex and 'B' trades but what are 'D' trades ? Also, a unit listed - 2 (P) DB. RE - that has stumped me. I know it's a UK based training establishment. Many thanks, Mac.
