Double-check the DD214 to see if you have the correct unit, 271st Infantry Regiment. While I found a load of information on them, Bob may have been on to something when he said 27th Infantry Regiment. So check the numbers.
The 271st Infantry Regiment was part of the 69th Infantry Division "Fighting Sixty-Ninth".
Anyway, chances are that he didn't serve in Korea or went into battle with the 271st Regiment, since the regiment was inactivated on 22 September 1945 and did not get re-activated until 1 May 1954 at Fort Dix, New Jersey. It is possible that this was his LAST duty station.
