In my civvy job I teach on- and off-road familiarisation to soldiers on MoD vehicles that shall remain nameless to protect the innocent. I'm also in the TA but these vehicles are not on my FMT 600, because my unit has not sent me on the approved course of instruction. I could get one of the other instructors to sign my FMT but there would be no record of my course bid/attendance held by the Unit. Could I drive them them with my green skin on given that although no army paper trail exists; I would be able to demonstrate competence to anyone who wanted to know? Master drivers & TCWOs, you opinions please.
