Many military records, especially Army and Air Force records, were destroyed by a fire in 1973. The records were kept in St. Loius.
From the National Personnel Records Center website: The fire destroyed "80% of the Army records (1912-1959) and 75% of the Air Force records (1947-1963). However, in some cases alternate sources were used to reconstruct some basic service information. There may be restrictions on who can order these records."
The NARA website mentioned by Nick has more information.
