JOINT BASE LANGLEY-EUSTIS, Va. – An emergency response exercise will be held at Langley Air Force Base on Tuesday.
The exercise will test the installation’s response to an emergency incident or accident, according to a press release from base officials.
There is expected to be minimal impact as a result of the exercise to daily operations and routines on base, but some local residents may see an increase in emergency response activities or hear simulated explosions or gunfire.
