! I'm thinking Airforce or Navy. What do you think?
Examples:
General Washington- 1st president
Teddt Roosevelt
President Grant
All officers in the military
All fine examples, though if you're aiming at President, you may wish to take note of the following:
William Henry Harrison - began military life as an ensign in the Army - only lasted a month as President; couldnt handle the weather.
James Garfield - began military life as a lieutenant colonel in the Army - only lasted six months as President; poor doctoring.
Chester Arthur - began military life as a brigadier general - three and a half years in office; didn't even have to run for President.
Franklin Roosevelt - was a state senator before he became Asst. Secretary of the Navy; didn't finish his last term.
James Buchanan - began military life as a dragoon; completed one whole term as President.
Grover Cleveland - paid someone $150 to take his place in the Civil War - served two terms as President.
There are other examples, such as Zachary Taylor, Andrew Jackson, Harry Truman and William McKinley. The point is: if you insist on military service before becoming President, be a dragoon. Otherwise, your chances for longevity are better if you enter military life as a general.
