My Uncle was a Marine Sgt. who was in the invasion of Iwo Jima.
My Mom was a 2nd Lt. Army field nurse.
She was awarded a Bronze Star for service behind enemy lines in Burma.
Both were @ Iwo Jima, Mom ended up there waiting for the invasion of Japan.
My Uncle gave to me the Colt 45 he used and its now a family treasure
For the Marines, the burial ceremony is different from the Army.
Who Knows the difference and the historical reason ?
