The Special Response Unit is made up of specialized teams that step in when a situation goes beyond routine patrol work. Whether the call involves explosive devices, an emergency on Fairfax County’s waterways, or a search beneath the surface, these units combine advanced training, specialized equipment, and rapid response to protect the public, recover evidence, and keep the community safe.
Explosive Ordnance Disposal Unit

The Explosive Ordnance Disposal (EOD) Unit handles situations involving explosives and other dangerous devices. Their job is to prevent explosions, protect lives, and safely neutralize threats.
Responding to Bomb Threats
When someone reports a suspicious package or calls in a threat, the bomb squad investigates. They assess whether it's credible and determine the level of danger.
Identifying Explosive Devices
They examine suspicious items to figure out what they are, anything from homemade explosives to military-grade ordnance. Bomb squads rely heavily on specialized gear to reduce risk:
- Robots to approach and inspect devices remotely
- Portable X-ray systems to see inside suspicious packages
- Bomb suits that provide blast and fragmentation protection
- Disruptors (tools that disable devices, often using water charges)
Disarming or Neutralizing Bombs
If a device is confirmed, they carefully render it safe. Sometimes that means disabling it piece by piece; other times they perform a controlled detonation in a safe area.
Handling Military Ordnance
They're often called when old grenades, artillery shells, or other unexploded munitions are found.
Supporting Investigations
After an incident, they collect evidence to help identify who made the device and how it was constructed.
Public Safety Sweeps
Before large events (concerts, sports games, VIP visits), they check venues for potential threats.
Bomb technicians undergo extensive training in:
- Electronics and wiring
- Explosive chemistry
- Robotics and remote operations
- Tactical decision-making under extreme pressure
Bomb squad work is high-risk, highly specialized, and focused entirely on saving lives by preventing explosions before they happen.
Marine Patrol Unit
Underwater Search and Recovery Unit
In addition to operational duties, the Dive Team actively engages with the community and supports partner agencies. Highlights include participation in events such as the Polar Plunge and Touch-a-Truck, as well as providing assistance to other law enforcement and regional dive teams when needed.
