Two thousand soldiers went on a 2.5-mile run at Fort Sam Houston to celebrate the Army's 238th birthday.
They started at the historic Army North Quadrangle and ran past some of the most historic sites at the base.
Maj. Gen. Perry Wiggins said the jog offered time to reflect on the Army's past.
"I think it helps soldiers connect with the physical nature and the history. When you walk through Ft. Sam Houston, for example, you actually can see the history," he said.
"It's a good chance to celebrate their birthday by getting all the units together here on post and going for a good old-fashioned run," said Staff Sgt. Jason Kniskern.
After 238 years, Wiggins said it is worth celebrating where the Army started and how far it has come.
"We have changed in equipment. We have changed in the faces, but really our true nature, our core, has remained the same," he said.
