Members of the Kentucky National Guard swarmed Keeneland on Tuesday morning, but it was only part of a drill.
The guard's Civil Support Team carried out an exercise demonstrating their response to a chemical or biological emergency. This particular team specializes in weapons of mass destruction.
The mission of the Civil Support Team is to support local and state officials during domestic incidents by identifying agents and substances, assessing the consequences, advising on response measures and assisting with requests for additional support.
This National Guard unit is required to undergo an evaluation like this every 18 months.
