I never thought he was in WWII. They always said he was "in Korea," and Sterling was the one who was in WWII.

If you have any doubts about the validity of any Wikipedia article, assume it is wrong. The great thing is that folks that are knowledgeable can contribute articles. The bad thing is that folks that *think* they are knowledgeable can also contribute articles.

You're basing the entire explanation of Bruno's question that Wikipedia is wrong? Have you thought that perhaps this show just has some errors in it? Because most of what Bruno has presented is stuff I remember straight from the show, in addition to well-known facts. Unless you're saying that Wikipedia is incorrect about the years of the Korean War (which I highly doubt), Bruno's whole issue boils down to this:
The Korean War was from 1950-1953. Season 1 is in 1960. In-between, Don supposedly packed in about 15-20 years into 7-10.
