The war began in June of 1950 when North Korea invaded South Korea, and ended officially with a negotiated armistice on July 27th, 1953.
Ron Sears of Cambridge, from the local chapter of the Korean War Veterans Association, says few people realize how important it was that United Nations forces, including the US, defended South Korea.
"Number one, it was one of the first times we stopped the Communist aggression. And number two, it liberated the South Korean nation and made them a very prosperous and free, democratic nation."
Sears served in the Army, and says while he was home on leave during the war, his friends didn't know he'd been fighting in Korea for more than a year, and also didn't know where Korea was.
The ceremony begins at 10 am Tuesday in the National Cemetery, with keynote speaker Colonel Todd Allison, the Arsenal's Garrison commander.
