I can only offer my own observations, which may or may not be similar to other expressed here.
To start with, I was raised to join. There was no doubt in my mind growing up. I was pretty well prepared when I got there, which is more than I can say for a lot of my fellow squids.
Actual on the job routine was similar to what I'm doing today. That is, I get up, I take a shower I go to work. Yes, we had occasional formation (and yes I squeaked about them) and yes we had to sit through at least one GMT (General Military Training, or Gross Missuse of Time , you make the call) but at the end of the day it wasn't that bad. I worked 12 hour toejamfs and had 3 days on, then three days off. As I Russian Linguist my job was boring boring boring borgin boring holyshitwhatthehellwasthat boring boring boring.
When I look back now, I'm amazed at how much we drank, but frankly it wasn't all that much more than dedicated college kids drink. I believe "Party like Rock Stars" was the catch phrase. I've puked in several countries, got rolled in Hong Kong, beat senseless in Hirosaki, and had to spend 300 bucks to catch the bullet train from Tokyo to avoid being U/A (AWOL) once. Am I proud of this? it was just stuff we did. We didn't have to drink so much, in fact there were pleanty of folks who didn't. But hey, we were sailors, we had a rep to protect.
Going to sea was alltogether different. 12 hours on 12 hours off. Not day off unless we hit a port. Then everyone shuffles off the boat, 95% get drunk, 80% get laid, 100% blow a huge chunck of money. You find comfort in the routine, I guess you don't have a choice. Our Ships library (on the USS Bunker Hill) had pleanty of books to keep you going for a short trip. I read Joe Foss's autobio, as well as Boyingtons (3rd time) and one called "Salvation for a doomed Zoomie" which was a pretty cool story about an F6F pilot who got shot down and served aboard the rescue sub that picked him up. He was Air and Sub Qualed at the end of his trip.
But through it all, the formations and the GMT, the shift work and the toejam work. The fair winds and fowl, you had your shipmates. If you went through a tour in the armed forces and didn't make any friends for life, I honestly pity you. People can troll about jobs and McDonalds and all, but there are some Amazing and Loyal people serving in our Armed Forces, and perhaps that is the most lasting a memorable part of my service, and the part that continues to this day, despite my having been out for Five years.
