San Diego, California - U.S. Navy security personnel and the Naval Criminal Investigative Service (NCIS) teamed up in active shooter training during Exercise Solid Curtain/Citadel Shield on Naval Base Coronado, February 25.

Exercise Solid Curtain/Citadel Shield is an annual exercise that assesses the readiness of Navy security personnel to respond to threats located on naval installations and individual units.

"This week the Navy is testing its security systems," said Master Chief Master-at-Arms Jonathan Rowcliffe, assistant security officer, Naval Base Coronado. "Right now we're focused on active shooter and hostage barricade, so today you're seeing what our naval security force and NCIS agents do in the event of an active shooter."

The exercise began when a belligerent active shooter entered the Naval Exchange (NEX) located on Naval Base Coronado. With a fake shotgun in hand he shouted, "BOOM, BOOM" voicing fake shotgun blasts.

"It was quite intense," said Master-at-Arms 3rd Class Alex Seebrey. "It would be a very scary situation if it happened in real life."

It took only minutes for naval security forces and NCIS agents to arrive to take down the simulated active shooter.

"As a naval security force member, what we want to see is people doing the job they are trained to do," said Rowcliffe. "Without this training program, we could not reach the level of expertise we need to assess and take on the threat."
