Nimoy enlisted in the United States Army Reserves in the early 1950s. Not a lot is known about Nimoy’s service time after his personal records were destroyed in a fire in 1973. We do know that the actor spent 18 months in the reserves, and his service number was ER 11 229 770. It is believed that Nimoy spent most of his time at Ft. McPherson in Georgia, and was discharged in 1955 having earned the rank of sergeant.
