4TROOPS, four combat veterans of the United States military will honor America before the Food City 500 March 21 with a rousing rendition of The Star-Spangled Banner.

The four military members all have served on the front lines in Iraq and Afghanistan. During their respective tours of duty they, came together to sing at large military events, as well as more somber occasions such as memorial services, where they sang to remember those troops who lost their lives fighting for our country.

The mission of the group, comprised of Cpt. Meredith Melcher, Sgt. Daniel Jens, Staff Sgt. (Ret.) Ron Henry and Sgt. David Clemo, is to sing on behalf of all troops, to honor their sacrifices and to create awareness for their needs.

Melcher, 29, is the daughter of a retired three-star General. She served as platoon leader on the front4Troops lines of Iraq where she led her troops in the successful ambulance evacuations of hundreds of wounded Americans and Iraqis. Jens, 36, served in Iraq and was most recently stationed at Fort Hood, Texas. He joined the army after the events of Sept. 11, 2001. Jens also was a finalist on "America's Got Talent."

Henry, 41, served in the Army for 20 years. He was a transport manager in Iraq with the 101st Airborne Division, and also the leader of the Army singing group "Transportation Express." Clemo, 30, served on the front lines of Afghanistan, providing communications and logistics support for the 18th Airborne Corps. He and Melcher toured together in 2004 with the Army Soldier Show.

4TROOPS recently signed with Sony Masterworks and in April the group's self-titled CD will be available with a portion of the proceeds from sales benefiting veteran-related charities.

The CD consists of well-known positive pop and country songs, along with some new songs. The first song, For Freedom, is an inspirational patriotic tune written by Matt Moran for his grandfather, a WWII veteran. Also included on the CD is the group's version of Toby Keith's hit Courtesy of the Red, White and Blue.

In March, 4TROOPS will embark on a U.S. Military base tour, followed by a national tour in the fall.
