U.S. Army Sgt. First Class Todd Reek, from the 44th Civil Support Team (CST), Florida National Guard, performs a proficiency screening for DNA in the CST's Chemical, Biological, Radiological, Nuclear and explosives test laboratory set up at Sun Life Stadium in Miami, Fla., Feb. 6, 2010. The laboratory can provide an onsite test on any unknown component found during searches to make an immediate identification of the substance. CST members from Camp Blanding Joint Training Center, Fla., are working with local and federal law enforcement units to scan delivery vehicles arriving at the stadium as part of the security efforts for Super Bowl XLIV.
