You only get A1 and B1 if you have a full civvie license. I had a G1 when I started my 404 process, G2 later on after I was already qualified Milcot, LS, ML + trailers and troop lift, but couldn't drive staff car or pickups. Had to do 2 roadtests before I could get the A1 B1.... woulda been easier to get my full G, but it was a 6 month wait after booking in Kingston at that point.
