I changed trades some years ago from infantry to Mse Op, and loved my job ever since. You will find it more relaxed, less anal retentive,( less armour protected - sorry, buddy , not intended as a cheap shot). Most truck drivers are suspected of masturbating frequently (most old truckers go blind), ...and ex- combat arms are often signified by what they have under their pillow when they sleep...if they're reeeeally asleep...hmmm.
Ql4 as you must know by now is dust of history, and the 5 course is tedious, mostly because you will by then know how to do things the right way, then you only get qualified by doing things the school way... then it's back to the Battalion to re-learn how to do it the right way again.
There are many good things about the trade, but the best for me, when leaving the pointy end of the stick, was the broader point of view - of the military, of my place there, of our job... and the freedom to think about things on those long trips by yourself in the cab. Welcome to the trade.
