I'm just stirring the pot here but is it time to subdivide the Med Tech trade? In the US army their 91W can get the M6 skill identifier which involves going through LPN training. That way you could have a certain percentage of Med Techs with the nursing skills of an LPN to work in the BMS etc. The Med Tech trade is so broad now I think most people are going to be hard pressed to maintain all their skills at any given time. It could be a separate branch off at the QL5 level similar to P Med Tech etc. This certainly wouldn't replace NO's but it could bring some additional nursing skills into a medical platoon.
