Officials at Dover Air Force Base are conducting a security threat exercise involving the scenario of an active shooter on the grounds of the Dover military installation.
Officials with the 436th Airlift Wing said Thursday's exercise will be conducted within the base and its training areas and will involve all base personnel.
They also say base visitors could be treated as participants, and that residents and guests should expect delays of customer service and possible gate closures.
Officials also advise that the exercise may involve simulated explosions, smoke, emergency responders and role-players with simulated injuries.
