"Both Agusta were first used by the Royal Marines and later used for SAS operations. I will look for their serials and complete stories at home. As far as I know, they are still in service in England.
Does anybody know what happened to the Army Chinook captured?"
This site has information on the Chinook:
Boeing's CH-47C Chinook in service to the country of Argentina.
Boeing's Mark 2 (HC2) Chinook helicopter.
