During a rehearsal at Ft. Jackson Regional Support Command Color Guard members, 1st SGT Thomas White, left, W4 Jeff Osler, SSG Jeremy Glasco and retired Col. John Boyd practice for their march in President Barack Obama's inauguration on Monday. The color guard is from the U.S. Army Reserve's 81st Regional Support Command called. "The Wildcats." They were chosen to represent Army Reserve Soldiers from nine southeastern states plus Puerto Rico. While at Camp (now Fort) Jackson in 1917, the 81st Infantry Division designed and wore the first shoulder patch of the U.S. Army - a wildcat on an olive drab colored circle. Celebrating the soldiers of World War One, the 81st Wildcats will proudly wear the Army's first patch on actual World War One uniforms while in the parade. C.
