So when I was a casual Lt back before ORE/ORIs ended having a forklift license was useful multiple times as opposed to waiting on loggies or MX folks to move our gear, and it even helped during a short notice ONE tasker. This was back when C-Models started coming apart and where grounded UFN and we needed to pack a bunch of stuff right before Christmas for a CONUS deployment.
Honestly, I think it would be awesome if all the Lts waiting for pilot training got trained to drive buses, fork lifts, etc. Because then the ops squadrons can just go to transportation check out the equipment, use it, and return it entirely on their schedule. Plus then it would be easier to screen for buffoonerous personnel before people bend airplanes. If you can't drive a bus or a forklift do we really want to trust you with an airplane?
