The U.S. Department of Veterans Affairs says Farber Specialty Vehicles will add 20 more so-called Mobile Vet Centers to a fleet of 50 it has built to be used in underserved or rural areas. Lawmakers and VA officials are expected to be on hand Wednesday to send off the first of those 20 new vehicles and announce where the new centers will be headed.

The mobile centers can be used for services such as health screenings, outreach and readjustment counseling for combat veterans and their families. The vehicles are customized for use on different types of terrain.
