These are images from Naval Weapons Station Yorktown's part of the Navy-wide training exercises Solid Curtain-Citadel Shield 2012.
The exercise Tuesday assessed the station's response to a Vehicle Borne Improvise Explosive Device attack.
Officials said it was a quick reaction, scenario-driven exercise to train and evaluate emergency first responders, which includes the Anti-Terrorism/Force Protection, Emergency Management, Fire & Emergency Services and Safety. Assets from York County Fire Department also took part.
The annual exercises are designed to enhance the training and readiness of Navy security forces to respond to threats to installations and units. The two exercises, each with a distinct focus, occur simultaneously and will stress different areas of the Navy's anti-terrorism program to enhance the training and readiness of Naval Security Force (NSF) personnel to respond to real-world threats.
