I’m probably recapping slightly, but the thing is that the military is… so very military. It’s an organization that runs on discpline and incredibly hard work and what at times seems like blind obidence to accomplish peculiar tasks and goals. It also is about preparing for war (destroying and killing); the intent is that the degree of preparedness will deter most or all “bad guys”. Knowing and thoroughly understanding that will put the young man into a mindset that should reduce the “culture shock”.
Also, what Critter says: Understand the “jobs” beforehand and prepare to get one accordingly. This applies to both officer and enlisted. To add to that, know that in the Navy there are jobs that require a high proportion of sea to shore time. For instance, a Radioman (which these days includes computer type people) might spend as much or more time assigned to land bases than ships, whereas someone who is (say) a “sea rate” like signalman or Bosun’s Mate might spend 5 years assigned to ships for every 3 to shore. Of course, understand that 5 years assigned to a ship doens’t mean 5 years constantly underway. And shore billets for a sea rate might well be assignments that do little or nothing to advance one’s skills or career. Joe Signalman might find himself doing 3 years as a gate guard at a Naval Station for his shore time. Joe Radioman might spend his shore time running the same Naval Station’s NT network, and do pretty much the same thing while assigned to a ship.
Let’s see… If I were going in now, I would decide if I wanted a strictly “warrior” type job (one that is “fun” in a macho way but doesn’t transfer to civilain employment directly) or a militarized version of a civilian job (blue collar or white collar). This has been referenced by Critter and others, but not put into the 3 categories.
The military is very hard on family life. The Navy, with long months at sea, is especially so. Nowadays, they try to accomadate some semblance of family life, but to some exent it’s still true that “if we wanted you to have a wife we’d have’d issued you one with your seabag” is still true.
Lastly, look to what UnoMondo said and read closely between the lines. What might be considered a really good, responsible, and prestigous job might also require an intense (intrusive) background check and constant questions about seemingly “off limits” areas of your personal life.
Being in the military means by definition that you sacrifice. A lot of your personal life is sacrificed, and sometimes your life itself. You have to be really, really prepared for that.
UnoMondo, I never met a SEAL that liked to kill. They are all --and I mean all-- the epitome of the word “dedication”. It always seemed to me that what they desired to do was to be so ready (well trained and equipped) to do whatever they were called on to do that their existence and reputation would deter the various potential opponents.
