TROY, N.Y. -- It was another day and another conspicuous venue for members of the New York National Guard's 2nd Civil Support Team as they trained to track down and identify hazards at Joseph L. Bruno Stadium here on April 12.

About a dozen members of the 2nd Civil Support Team (CST) participated in the training exercise, which was based on a scenario involving a clandestine weapons of mass destruction laboratory at the stadium. Team members are trained to identify chemical, biological, and radiological agents and advise first responders on how to deal with these materials.

Training at the minor league baseball stadium is right in line with their mission, said the 2nd CST Commander, Lt. Col. Aron Sacchetti, of Nassau, New York. Terrorists target such places in order to cause many casualties and incite widespread terror, he explained.

"We try to conduct training in public venues where there are likely to be large gatherings of people," he said. "This gives us familiarity with the venue beforehand and familiarity with security personnel at those places."

In this training scenario, stadium security personnel who discovered the lab began exhibiting signs of sulfur mustard agent exposure, including runny noses, irritated throats and other respiratory symptoms. The team's mission was to identify any hazards, then recommend mitigation measures and all other precautions to the incident commander.

Driving several vehicles -- including the 2nd CST's mobile laboratory, called the Analytical Laboratory System (ALS) -- team members arrived at the stadium around 10 a.m. and set up communications equipment, hazardous materials detectors and other gear.

Following briefings, 2nd CST members Sgt. Christopher Rodriguez and Staff Sgt. Joshua Spagnola, wearing breathing apparatus and orange hazmat suits, entered the stadium to conduct reconnaissance.

"We know when we're going in, we're facing something hazardous," Sacchetti said. "But we're equipped to handle those situations."

After locating the mock laboratory, Rodriguez and Spagnola undertook the painstaking process of identifying hazardous materials, tagging them with evidence markers, photographing each one, photographing the entire scene, categorizing hazards and collecting samples. Stocked with many simulated hazardous materials and other chemical processing equipment, the mock laboratory was intended to challenge the team members' skills.

Since their mission involves evidence collection, the team members' methodical approach is designed to prevent cross-contamination and tainting of evidence, said 2nd CST 1st Sgt. Noel Fredericks, of Schenectady, New York.

"This is definitely an attention-to-detail type of job," he said.

Team members work from general to specific, Fredericks explained, first determining if a substance is a hazard, then attempting to identify what it is. Sometimes a substance might be just an ingredient used in the making of WMDs, which is called a "precursor chemical."

"That chemical may be only used to make one thing in the WMD realm," Fredericks said.

Team members are trained to use a wide variety of different technologies -- from electronic devices to pH paper -- to detect and identify hazardous materials.

The ALS can analyze chemical warfare agents, toxic industrial materials, toxic industrial chemicals and biological warfare agents, according to an Army fact sheet. The ALS provides detection and identification capabilities to the CSTs to conduct an analysis of unknown or potential agents at an incident site and transmit that information electronically in support of the first responder incident commander.

"By collecting a sample and conducting more testing, we're able to confirm what it is," Sacchetti said.

According to Sacchetti, the team members completed the mission by 12 p.m. The 2nd CST conducts collective training of this kind about once a month, often with first responders.

"We try and incorporate our civilian counterparts as often as possible," he said.

The 2nd CST is based at Stratton Air National Guard Base in Scotia, New York. From that location, the team can deploy throughout upstate New York or the northeast.

The 2nd CST routinely sends teams to be on-call during major events that might be targets of an attack, like the Watkins Glen races, the U.S. Open, the opening of the United Nations General Assembly and the World Series.

The 2nd CST is one of two civil support teams manned by full-time members of the New York National Guard. The New York National Guard also maintains the 24th CST, which is based at Fort Hamilton, New York, and focuses on operations in the New York City metropolitan area.
