In the Navy is has to be a striker, an enlisted individual who has not chosen an NEC (Navy-speak for MOS), and is loaned around to several shops to see what they have an interest or inclination in, then get OJT, then sent to A school. Sounds good, but they often end up as a deck ape and chipping paint. My other thought is any one of the food service/mess NECs/MOSs. They are so valuable and work their collective butts off, but get little respect. An old Chief told me to make friends with the mess cranks. I did. What sage advice.
Regarding the 1911: "The gun was designed to function. If it's built to the proper specs...it'll run. It's a machine. It doesn't have a choice." 1911Tuner
