A Marine expeditionary unit deployed to Fort Pickett is conducting nearly two weeks of training in and around populated areas in Virginia. Most of the 2,200 Marines and sailors from the Camp Lejeune, N.C.-based 22nd Marine Expeditionary Unit will train at Pickett, but small groups—80 to 100 Marines—will perform three exercises at other locations, according to the 22nd’s spokesman, Capt. Clark Carpenter.
