Confidential reports on officers who served during World War One and who, in some cases, continued serving beyond World War Two have been added to ADM 196.

Service records of executive officers who joined after May 1917 are not held at The National Archives.

These records are held by the Ministry of Defence who will release information to the officer, or to a next of kin, for a fee. Details can be found on the Ministry of Defence's website at http://www.veterans-uk.info/service_records/service_records.html
