In 1927, Laycock was commissioned into the
Royal Horse Guards. After the
Second World War broke out he raised and trained the
commando unit
No. 8 (Guards) Commando (8 Commando). This unit of 500 officers and men was to prove influential: one its sections, encouraged by Laycock, was an experimental marine section, known as the "
Folboat Section", which ultimately developed into the
Special Boat Service; and one of its officers,
David Stirling, would go on to found the
Special Air Service. Laycock was promoted to
lieutenant-colonel, and appointed leader of the eastern Mediterranean
commando force "
Layforce", named after him. This combined
commando force, which included 8 Commando and four other
commando units, operated from February to August 1941, and saw action in Libya (
Bardia and
Tobruk),
Crete, and Vichy Syria. It had mixed results, but developed commando warfare. In the
Battle of Crete Laycock was one of the last officers to leave the island (along with his intelligence officer
Evelyn Waugh), when it was evacuated by British forces at the conclusion of the battle in May 1941. The main role of the commando force on Crete had been (atypically) to cover the evacuation of the rest of the British army, and much of the Layforce unit of 800 men was itself unable to get away: 600 of them were captured by the German army.
Evelyn Waugh was an admirer of Laycock, and later dedicated his novel
Officers and Gentlemen, which is set in this period and theatre, to him. Laycock commanded the Middle East Commando from August 1941 to August 1942, in
North Africa,
Sicily and
Italy. He then returned to the United Kingdom, was promoted to
brigadier, and from 1942 to 1943 commanded the
Special Service Brigade, which organised and trained all commandos in the United Kingdom. In 1943 he was promoted to
major-general, and became Chief of Combined Operations, succeeding
Louis Mountbatten. He held that position until 1947. . Standing behind is Lieutenant Colonel Norman Charles Ries, CO of
