'FLOATING' TEETH From left to right, Army Sgt. Brian Roebuck, Ron Roller, 1st Sgt. John Wear and Sgt. Tommy Evans "float" Bill's teeth at the Commanding General's Mounted Color Guard stables on Fort Hood, Texas, March 15, 2012. Roller is the unit's civilian trainer. A domesticated horse's diet does not allow for even wear of its teeth, creating sharp ridges on the sides. The process to smooth the ridges is called floating, and requires a special tool attached to a drill. SHARE: Download: Full Size (0.07 MB) Credit: VIRIN: 009401-E-MJE94-086.jpg Photo Gallery
