The 1966 Defense Department annotation reads:
1st Marine Aircraft Wing (1st MAW). Photographer: Sergeant (Sgt.) Hathaway. CHRISTMAS VIGIL–A Marine sentry, Lance Corporal Glenn L. Mitchell of Washington, D. C., and his dog, "Chief," patrol a lonely perimeter near Marine Aircraft Group-36 (MAG-36) in Vietnam and pause before a cross near the group chapel. The Marine's thoughts reflect the hopes of servicemen around the world the Christmas season, "…peace, on earth, good will to men."
Is it futile to wish for peace each year? I hope not.
