General Sir Mervyn Andrew Haldane Butler, KCB, CBE, DSO & Bar, MC (1 July 1913 – 3 January 1976) was a British Army officer who served as Commander-in-Chief Strategic Command.

[1] During the Suez Crisis elements of the 16th Independent Parachute Brigade led by Butler and a contingent of the Royal Tank Regiment set off south along the canal bank on 6 November 1956 to capture Ismailia.

There were Egyptian forces ahead; the British column was in open desert with no defensible feature to hand.

Butler compromised, advancing until 0:15 am on 7 November 1956 to reach El Cap, where he sited the 2nd Battalion of the Parachute Regiment, with supporting detachments.

[9] In 1964 Butler was appointed Assistant Chief of Defence Studies (Joint Warfare) and then in 1966 went on to be Commandant of the Staff College, Camberley.
