If you join the military, especially the infantry, with a hidden agenda you won't be successful and you
will hate life. You're going to hate life regardless but if you're uncommitted and/or think you can get away with being an individual as a junior soldier or Marine, well, see what happens.. It's possible to "quit" before the end of recruit training but they don't make it easy for you because they're trying to make good on their investment. In addition to that you are far from combat-ready during this initial phase of training; the valuable training comes after the indoc. Infantry training is only useful if you're 100% with the program. Enlisting to acquire "combat skillz for _insert Turner Diaries scenario here_" is a
bad reason to join the military. And by bad I mean fucking stupid.
good reasons to be a grunt:
- want to kill people
- want to do something dangerous/heroic
- seriously interested in weapons/tactics (i.e., modern military weapons/tactics, not LARPing)
In other words: someone who wants to experience combat and is willing to get killed for it or worse.
Before their first deployment enlisted grunts acquire a 'combat mindset' (confident and aggressive), become competent/proficient with a handful of individual and crew-served weapons, learn basic military tactics, and may get an opportunity to learn small unit leadership.
Oh, I almost forgot. Eggheads make terrible grunts.

I'll tell you why: without a combat mindset, without mental preparedness, martial skills and knowledge are useless. Now some of you may be still have that curiosity about combat, killing, etc. You want a challenge, you want to push yourself. Good for you. Just give yourself an honest self-evaluation before you do something which will do you more harm than good. Sensitive minds (artists, intellectuals, social introverts, etc) generally do not do well in the military and certainly not in the infantry.
