Hey, I thought I was the only 'Bee on the boards. I’m a retired CE Chief.
Raguleader: As a Seabee, I spent 23 years and never set foot on one of those floating petri dishes. The Seabees are the construction arm of the Navy and are almost exclusively shore-based. You still deploy for months on end, but it’s in places where you can change into civvies and go out for a beer after work. The downside is that in a war situation, you’re in the thick of it.
Re your question about commissioning: the possibility is nearly zero. While there are “mustang” programs for enlisted persons, such as the LDO (Limited Duty Officer) program, the competition is very tough. You would be better off getting your degree first, then trying for OCS before signing up.
I would rank the services thusly:
Navy: pros - better promotion, interesting duty assignments, good schooling; cons - deployment cycles can by hell if you have a family, but sea duty is followed by lengthy shore duty assignments.
Air Force: pros - better food, better quarters, more informal; cons - poor promotion, crappy assignments, surrounded by pussies.
Army: pros - easier to become commissioned officer; cons - as easy to be demoted as it is promoted, crappy food, people shooting at you, and (and I’m sure I’ll get basted for this) a generally worse quality of people to work with (the Army is not all that choosy about who they recruit).
Marines: pros - extremely high esprit de corps; cons (maybe) - hard-core physical requirements, very strong military discipline and regimen, the worst food and living conditions in the military, people shooting at you, AND you can end up serving on board ship anyway. I’ve known a lot of Marines over the years, and while I respect what they do and called many of them friends, they’re some of the dumbest motherfuckers I’ve ever run across. No offense. While you may not be the first ones to assault a position, the Seabees who greet you when you arrive will let you claim the honor.
