Major-General Sir Stephen Cyril Ettrick Weir, KBE, CB, DSO & Bar (5 October 1904 – 24 September 1969) was a New Zealand military leader and diplomat.

Weir was the successful applicant, with his experience as a school cadet and as a territorial a factor in the decision by the military authorities to award him the cadetship.

[3] During the transit to North Africa, Weir was commander of troops aboard the transport ship HMT Ormonde.

He had to deal with a near mutiny by some of the soldiers aboard when the ship stopped at Bombay, due to the poor quality food being loaded there.

[5] He had himself narrowly avoided being captured while supervising the retreat of the 6th Field Regiment during the Battle of Sidi Rezegh, the same action that saw Miles made a prisoner of war.

[6] Promoted to brigadier shortly after assuming command, he built on the work of Miles and implemented measures to concentrate fire of the divisional artillery.

[3] Later that year, his work in co-ordinating the artillery efforts during the Second Battle of El Alamein earned him a Bar to his DSO.

The division was soon transferred to the Italian Front as part of the British Eighth Army, with Weir continuing as CRA.

In September, he was acting commander of the 2nd New Zealand Division while Freyberg recovered from injuries sustained in an aircraft crash.

The 46th Division supervised the disarmament of guerrilla forces in Greece, work which was personally recognised with Weir receiving the Greek Cross of Valour.

The division returned to the Italian front in April 1945 and then, on the cessation of hostilities, moved into Austria on occupation duties.

[2] His return to New Zealand was delayed due to serious health issues but he eventually took up command of the Southern Military District in 1948.

During this time he oversaw the abolition of compulsory military training, a government policy which he personally disagreed with but carried out to the best of his ability.
