From an ACPD press release:
The Arlington County Police Department’s (ACPD) Special Weapons and Tactics (SWAT) team will be conducting a training exercise at 3963 N. 26th Street on Tuesday, October 23rd between 6:00 am – 3:00pm. The purpose of the training is to simulate real life situation and a coordinated response in your neighborhood.
There will be no live ammunition used in this exercise. However, realistic looking training weapons that shoot paint projectiles will be utilized. Noise flash diversionary devices may also be utilized during this exercise. These devices will make considerable noise but do not dispense any munitions. The noise may be upsetting to small children, pets or those with sensitive hearing. If someone in your household falls into one of those categories we ask you take precautions you believe are appropriate.
Numerous Police vehicles will be parked in the area. These vehicles will not block any driveways or the right of way on the road. Should a vehicle need to be relocated because it is blocking your access, please contact one of the on-scene control officers for assistance. The control officers can be identified by the bright yellow traffic control vests they will be wearing.
Thank you in advance for your cooperation. Realistic training is critical to enhancing our capabilities to serve and protect you to the best of our ability. Your patience and understanding is greatly appreciated.
