As part of another grant, a group of Washington D.C. metropolitan area fire departments received large Medical Ambulance Buses for mass casualty incidents. Seven were delivered - Loudoun County, Arlington County, Fairfax County, Washington D.C., Montgomery County, MD (2), and Prince George's County, Maryland.
Loudoun's Medical Ambulance Bus (MAB) was originally kept at the Training Center and then transferred to Station 23 in 2009. It is a 2007 Thomas Built Bus outfitted by Sarton Services.
This photograph was taken next to the burn building at the Training Center shortly after being placed into service.
