## Military career
### First World War

Leask joined the British Army soon after the outbreak of the First World War, being commissioned as a temporary second lieutenant in the 11th Battalion, Devonshire Regiment on 19 November 1914, just after his 18th birthday. The 11th Devonshire was a reserve training battalion, based in Wareham, Dorset, which provided the 8th and 9th Battalions, serving in France, with reinforcements and replacements. Leask was later transferred to the Machine Gun Corps, serving as an instructor.
Leask transferred into the Royal Flying Corps (RFC) in May 1916, and was granted Royal Aero Club Aviators' Certificate No. 3673 at the Central Flying School at Upavon on 20 July. He was appointed a flying officer, and transferred to the General List, the same day. He was assigned to duty with the RFC on 1 October, and was posted to No. 42 Squadron, flying B.E.s until December, when he transferred to No. 41 Squadron flying F.E.8s. He was appointed a flight commander with the temporary rank of captain on 10 January 1917, and in May he returned to England to serve as an instructor. He later joined No. 84 Squadron, taking command of "A" Flight, and returning to France in September. Flying a S.E.5a, Leask gained his first aerial victories on 21 October 1917, when he and John Steele Ralston drove down out of control a German Type C reconnaissance aircraft east of the Roulers–Menin road, and twenty minutes later Leask drove down an Albatros D.V solo. He drove down another D.V over Menin on 31 October, and destroyed another reconnaissance aircraft south-east of Bouzincourt on 30 November. His fifth victory came on 30 January 1918 by driving down another D.V over Villers-Outréaux, making him a flying ace. His last three victories came in March, with three more D.Vs, two destroyed and one driven down, on the 6th at Renansart, the 18th at Wassigny, and the 23rd north-east of Ham.
Leask was awarded the Military Cross, which was gazetted on 26 March 1918. His citation, published on 23 August, read:
   Second Lieutenant (Temporary Captain) Kenneth Malise St. Clair Graeme Leask. Devonshire Regiment and Royal Flying Corps. For conspicuous gallantry and devotion to duty in leading offensive patrols against superior numbers of the enemy. His patrol twice engaged more than double their own numbers and drove the enemy back into their own lines. He drove down three enemy machines, which, were seen to be destroyed, and accounted for eleven in all. He showed splendid determination and initiative.
On 1 April 1918, the Army's RFC and the Royal Naval Air Service were merged to form the Royal Air Force (RAF). That day Leask flew his final sorties with No. 84 Squadron, making three forced landings. These were the last of over 100 operational missions he flew with the squadron.
On 21 June Leask was awarded a second Military Cross. His citation read:
   Second Lieutenant (Temporary Captain) Kenneth Malise St. Clair Graeme Leask, MC, Devonshire Regiment and Royal Flying Corps. For conspicuous gallantry and devotion to duty. He attacked a formation of five enemy scouts, one of which he destroyed. Later, he carried out a very valuable reconnaissance at a height of 160 ft (49 m) in order to locate the enemy's position. While thus engaged he observed a large column of enemy troops advancing along a road. He dived down to a height of about 30 ft (9 m) and attacked and scattered them, and held up their advance for a considerable time. He has done splendid work in attacking enemy troops from a low altitude, showing great courage, and determination under heavy fire.

### Inter-war career

On 1 August 1919 Leask was granted a permanent commission in the RAF with the rank of flight lieutenant, resigning his army commission the same day.
