The Las Vegas Metropolitan Police Department (LVMPD) SWAT team, one of the most active in the country, routinely serves high-risk warrants and responds to barricade and hostage scenarios. Dr. Carrison and Dr. Berkeley both serve as tactical physicians for the SWAT tactical medicine program.

The tactical physicians are involved in the initial mission briefing with the SWAT team, which includes review of the schematic layout of the target location and the tactical plan. During each scene response, the physician and a tactical medic, who is also an officer with Search & Rescue, are deployed in a tactical rescue vehicle (TRV). The physicians wear body armor and are on-scene as the SWAT team clears the site, either dynamically (rapid breach entry, with possible use of explosives and/or distraction devices) or tactically (slow and methodical).

Drs. Carrison and Berkeley are tasked to stabilize any individual on-scene with an injury or acute medical condition, utilizing the principles of Tactical Combat Casualty Care (TCCC), with prioritization depending on the level of injury and the tactical situation. They are actively involved with ongoing tactical medicine training, including simulated downed-officer and multiple casualty scenarios, advanced airway management skills labs, and live-fire exercises.
