I have yet to meet a piece of machinery that knows or cares how well an engineer can march or play soldier.
When I got into Maritime I did not have any self discipline, really. The regiment didn’t serve as a pretend military game, as some say… it taught me to take care of myself and my belongings, keep a squared away living and work space and to strap on my boots and get on deck/watch/formation regardless of how hot, cold, wet or humid the conditions were or how miserable I was.
I can see your point, but I likely wouldn’t have gone to the school if it didn’t have a regiment. As much of a pain in the ass as it could be it was a major selling point for me.
