I believe he served in the US Army
Ya, he was in the Army in the early or mid ‘50s, if I recall correctly. His father pulled strings and got Ted stationed in Paris. Rumor has it that Ted enjoyed the company of French girls and French wine when he was there.
First, he’s a Kennedy, and has had a burial plot waiting for him since JFK died.
Second, Medal of Freedom recipients can be buried there. Ted Kennedy received one from Obama recently.
Third, the President and Congress can authorize anyone to be buried there through legislation. Ted Kennedy already has that.
From Wiki...Interesting....
Kennedy enlisted in the United States Army in June 1951.[10] Following basic training at Fort Dix, he requested assignment to Fort Holabird for Army Intelligence training, but was dropped after a few weeks without explanation.[10] He went to Camp Gordon for training in the Military Police Corps.[10] In June 1952, he was assigned to the honor guard at SHAPE headquarters in Paris.[4][10] His father’s political connections ensured he was not deployed to the ongoing Korean War.[4][11] While stationed in Europe he travelled extensively on weekends and climbed the Matterhorn.[12] He was discharged in March 1953 as a private first class.[10][12]
