Dust and sand falls off the tracks of an M1A1 Abrams Main Battle Tank, with 2nd Tank Battalion, 2nd Marine Division, as the vehicle moves off a railcar at Fort Pickett, Va., March 28, 2014. More than 350 Marines and sailors with the battalion will be taking part in the month-long, field exercise. Twenty-two tanks and four M88A2 Hercules Recovery Vehicles were unloaded from the railcars.
