USMC at Normandy?

[John Kepler]

Now the Marine commender in Korea, name was Smith (Howlin mad?),

Nope! Lt. Gen Holland "Howlin' Mad" Smith retired from the Corps on May 5, 1946 (with a "graveyard" promotion to General). He died in San Diego, CA, Jan. 12, 1967 at the age of 84.

You are thinking of Maj.Gen. Oliver P. Smith who commanded the 1st Marine Div. in Korea.
