Don’t be surprised if you hear what sounds like gunshots near the Pentagon this weekend. The Pentagon’s police agency is planning to conduct a “live fire calibration test” between 6:00 a.m. and noon on Sunday.

From a Pentagon Force Protection Agency press release:

On Sunday, Dec. 11, 2011, a live fire calibration test will be conducted by the Pentagon Force Protection Agency between 6 a.m. and noon. If severe weather is predicted, the test will be conducted during the afternoon of Saturday, Dec. 10.

Pedestrians near the area during the testing may hear firearm discharges and see testing facilitators with yellow safety vests. All activities have been coordinated with the Pentagon building safety office, security personnel, and neighboring jurisdictions. Safety during the test is a priority, and the Pentagon Force Protection Agency will be restricting vehicle and pedestrian access to certain locations around the South Parking Lot during this time.

If any individual or activity looks suspicious, please call 703-697-5555 immediately.
