Fair enough.
1. What do YOU want to do?
As a high school grad, you are not going to do much in the way of super cool. Only Officers BA-PHD's get that.

2. You would start below the bottom rung, and would have to prove your worth. It ain't easy.

3. The Army wants people who can follow orders, react to muscle engrained drills, shot straight, and have intestinal fortitude. Your vocabulary will have many words, and most will contain "Hooah" and "Kill". You can become a member of the "Golden Knights" or a "SPEC-OPS" operant. Only the best of the best are selected for "The Old Guard" the highest honor of the DOD, and is only selected from the Army, the senior branch.

4. The Marines only want a few GOOD men. They are totally re-programed from society, (16 weeks of it), and your vocabulary will consist of a few words, starting and ending with "Erp" and "Kill". You will learn to consume very large quanities of beer while on liberty, and will wear the shapest looking uniform in the entire DOD.

5. The Navy wants seamen.

6. The Air Force wants people who are capable of thinking outside the box, are motivated, dedicated, and understand that if the plane and pilot does not return, your future is in check until the investigation is complete. They demand critical skills, have a steep learning curve, and hold people to their actions. Not just the life of the pilot/crew rests in your capabilities, but millions of dollars as well, and possibly national security. Only the best of the best are selected for Air Force One and Two.

The Army fought the Revoluntionary war with General George Washington.
The Marines manned the guns at Tripol.
The Navy turned the tide of WWII with the Battle of Midway.
Some astronauts were Air Men.

Too easy, what else?
