Weapons Training Battalion (WTBN) aboard Marine Corps Base Quantico held a change of command ceremony June 30 at which Col. Timothy Parker relinquished command to Col. Peter Farnum. A unique twist to the change of command ceremony was the passing of the officer's campaign hat in addition to passing the colors. The campaign hat is limited to certain personnel primarily in recruiting, range/marksmanship, and rifle/pistol teams. - Weapons Training Battalion (WTBN) aboard Marine Corps Base Quantico held a change of command ceremony June 30 at which Col.
