Well here's something that will raise a few hackles but what the heck? Times change and a reasonable man has to face the truth.
I mostly want to get some info what it's lke in the military, Specifically the Coast Guard, Navy or Air Force when you enter as an officer.
All the fun stuff previous mentioned by others plus...
Do you like bureaucracy? Like a whole lot more bureaucracy than you ever had at any civilian job or school in your whole life? Can you handle calling Obama or Clinton your commander in chief for the next four to eight years and having to display public respect for them on at least an occasional basis?
Can you handle the cognitive dissonance of first swearing an oath like
"I, _____, do solemnly swear that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; and that I will obey the orders of the President of the United States and the orders of the officers appointed over me, according to regulations and the Uniform Code of Military Justice. So help me God."
or
"I, _____, having been appointed an officer in the Army of the United States, as indicated above in the grade of _____ do solemnly swear that I will support and defend the Constitution of the United States against all enemies, foreign or domestic, that I will bear true faith and allegiance to the same; that I take this obligation freely, without any mental reservations or purpose of evasion; and that I will well and faithfully discharge the duties of the office upon which I am about to enter; So help me God."
And then
A: Do the bidding of people like Clinton or Obama and Schumer and Feinstein and Kennedy and a whole host of others who took a very similar oath which they hold in contempt to put it mildly.
B: Never, ever get used to actually defend the Constitution of the United States or defend freedom. Instead you'll get to watch as you pour your heart and soul into hoping and trying, probably losing a few really great friends along the way, and still seeing our supreme law of the land used for toilet paper while the weasels go nuts ripping our country apart.
If you don't care about that stuff then you'll probably be happy as a clam. I'm one of those high minded idealists though and I just can't see willingly taking a job as a government employee to be the muscle for our current corrupt anti-American anti-Constitution regime. If you want to defend freedom then vote, run for office, work hard to wake other people up, that kind of stuff. If you want to help keep your fellow Americans safe buy a pistol and get a concealed weapons license or lobby to get concealed carry laws passed in your area. Concealed carry is proven time and again to actually reduce violent crime rates plus only an armed populace can ever hope to have any measure of security against random attack be it your garden variety psycho like the mall shooting or a terror attack like 9/11. Only armed citizens can be everywhere at once. If you want to defend American sovereignty then go join the Minute Men down on the border so you can at least have a chance at doing something that keeps invaders out. EMT or fire rescue still let you do some real good too.
The point is there are a million other completely lawful outlets for the natural and manly desire to serve one's society and do some good that are a lot more effective than being a tool for some stooge politicians. You always hear some chucklehead or another on one gun board or another talking about rebelion this, come and get them that, cold dead hands, is it time yet?, blah blah blah. Empty words and pointless garbage. What makes a whole lot more sense is to stop playing games and start acting like Americans again. That means stop helping the politicians stab us in the back and start taking individual personal responsibility and taking active roles in our community again. It should be obvious to anybody that state run collectivism in any form is a bad joke for anybody who cares about the cause. Try this one on for size, is the second ammendment and individual or a group right?
The Coast Guard on average is probably your best bet if you're looking for a branch that still mostly gets used the way they should be. Of course that is changing and will continue to change as we get deeper and deeper into the paranoid security state mentality that is sweeping the nation but that's just life in our age. I have much respect for rescue swimmers.
