No, he did not. But these days, that is not unusual. Back in the era before President Obama was born, there was a military draft and young men had to register for it; there was the Korean War, and then the Vietnam War going on, so large numbers of American young men were called to serve. Many members of congress in the 1960s and 1970s (more than 75% by some estimates) had already served in the military, and it was a common experience for that generation.
But now, there is no draft, and many fewer members of congress (about 20% currently) have had any military service. That includes President Obama, who was a former US Senator-- by the time he was growing up, there was no more draft. And with no wars to go fight, he was one of many who never entered the army, navy, marines, air force or coast guard. But as Commander in Chief, Mr. Obama, like each president, is in charge of the military and oversees military strategy, along with his chosen Secretary of Defense.

None. President Obama was too young to serve in any previous major wars.
Yes, nearly 15,000 US Marines died in Vietnam.
MARINES
You can find Marines in any country the US has an Embassy. The Marines provide security for all of the US Embassies, including Bolivia. There has been no deployment there.
If you have a tattooed chest, you can still serve in the marines.
You let your enlistment with the Navy expire and then join the Marines. There is no 'transfer' between the two units. If you are a Corpsman, you can be asked to serve with the Marines.
No, you do not have to sell your soul to join the Marines. Joining the Marines entails making a commitment to serve in the military and uphold the values and mission of the Marine Corps, but it does not involve any sort of supernatural or metaphysical exchange.
Wilson never served in the Marines, or any other branch of the US military.
President Obama was too young to serve the last time the draft was in effect.
You can't.
