On Friday Ellsworth “Al” Johnson officially received the U.S. Army Special Forces tab and beret. He is 100.

Johnson was a World War II veteran who served in the Office of Strategic Services’ Operational Group in France and China. The Army had determined that the centenarian met all of the requirements to join the regiment.

“This is an extremely rare event and, quite frankly, the last of its kind that will ever occur. We are all excited to welcome Mr. Ellsworth as a member of the Special Forces Regiment,” Major Russell M. Gordon, 1st Special Forces Command’s director of public affairs, said.

Johnson was presented with a Special Forces badge and a green beret on Friday, Sept. 1 by 1st Special Forces Command head Brig. Gen. Gil Ferguson and Army Special Operations Command’s deputy commander, Maj. Gen. Patrick Roberson. Johnson was joined by his family at the Riley Grove Assisted Living Center in Michigan where he lives.
