Corporal Thomas J. Johnson, a vehicle commander with Anti-Tank Platoon, 2nd Tank Battalion, 2nd Marine Division, from Roanoke, Va., throws an M69 Training Grenade at Fort Pickett, Va., during a Hand Grenade Familiarization Training March 31, 2014. “Throwing grenades properly and on target is a perishable skill. It’s kind of like throwing a baseball after a year off the field,” said Cpl. Patrick W. Westcott, a Tiverton, R.I., native and team leader with Scout Platoon.
