Obviously as we all know with these roles being specialist, it is only promotion from a general role in the same field that enables someone to get these roles. My question is, which one would be the most likely for someone to gain promotion. I might get a response from a few asking me, "well how longs a thread of string?" but we all know there are roles which are regarded more suitable to make that transition from than others... Armoured Engineer Plasterer / Painter Bricklayer Carpenter And Joiner Building Materials Technician Elec & Mech Draughtsman Design Draughtsman Survey Engineer Building Materials Technician Engineer Specialist Driver Fabricator Electrician Air Conditioning Fitter General Fitter Engineer Logistics Specialist Plumber Plant Operator Mechanic Engineer Troop Officer (I only have the equilivant to A-Levels so not sure this would even be an option) Note: I don't drive, so if people could list the best route when considering the driving roles and the best without considering them. Thanks.
