This was an amusing read....
On the joys of being a Supply Officer, my best tours are the ones where I'm doing legit work to make the Navy operate better. Being in the room or leading the big picture issues and answering, "OK here is THE Navy, how can we get THIS part of it to the fight quicker/better/stronger?" In these tasks, you can't help but feel indispensable to the command and the Navy at-large. And if you do it well enough, you will have an operation or support network that will last long after you depart or until the next guy messes it up, lol.
I also second the notion that ashore the Supply Corps takes very good care of the front runners via civilian education, followed up by payback tours utilizing that experience. For example we send LTs on tours to get a Masters in Petroleum Management then send them to a fuel farm tour to utilize it. These guys are VERY taken care of in the fleet and when they leave the service.
On the flip side, I can't put words to how absurd some of the BS can be. Seeing a grown adult and Senior Officer get legit Hitler/Downfall scene pissed over ice cream while you struggle to not laugh because he or she is the XO..... or my favorite, "SUPPO we failed the mission/exercise/inspection/spotcheck etc because you didn't have the foresight to predict the requirement we never told you!" It never gets old.....
CVN O-5 and LT DH Afloat tours are our "proving ground" tours that determine Command and O-4 selection respectfully. If you can put up with the known circus of headaches and walk away clean, you get to move up.
