JOINT BASE MCGUIRE-DIX-LAKEHURST, N.J. -- Senior Master Sgt. Osmond Silvera, serving in the role of urinalysis observer, looks on as Staff Sgt. Elvin Paulino, 514th Aeromedical Evacuation Squadron, receives a specimen bottle for urinalysis. Observers ensure proper procedures are followed throughout a urinalysis test. Air Force Reserve Command implemented a new instruction for urinalysis that randomly selects 25 percent of members per month for testing, up from two percent with the old policy. Some members may be selected more than once in a given period, while others not at all. Sergeant Silvera is a member of the 714th Aircraft Maintenance Squadron. (U.S. Air Force photo/Staff Sgt.
