About 2,200 Marines and sailors are conducting nearly two weeks of training around Virginia.
The Camp Lejeune, N.C.-based 22nd Marine Expeditionary Unit is training at Fort Pickett in Blackstone. But officials say they also will perform smaller group exercises at other locations.
Military officials say training in towns can give the unit experience dealing with urban areas.
Residents may see Marine vehicles on roads and aircraft from the Marine unit flying overhead and practicing setting down in previously cleared landing zones until Jan. 24.
The unit is preparing for a scheduled spring deployment overseas aboard several Navy amphibious ships. The Virginia work-up is part of a 26-week training program.
