Operation Cottage at 75, or the time the Canuks were really welcome in Alaska
Here we see a well-kitted Canadian corporal, probably of the 13th Brigade (consisting of the 2/Canadian Scottish, 1/Brockville Rifles, and 1/Edmonton Fusiliers), inspecting a captured Japanese Type 96 or 99 light machine gun, on the foggy and windswept island of Kiska, in the Aleutian chain of the U.S. Territory of Alaska, 16 Aug 1943.
As a sideshow to the Battle of Midway, the Japanese occupied Kiska with 500 IJN Special Landing Force marines on 6 June 1942 and, though they reinforced the garrison with another 8,000~ sundry troops to include a mini-sub base, by 28 July 1943, they shagged ass when it appeared the U.S. was coming back to take the island in force– one of the very rare instances when the Japanese withdrew from an island rather than fight for it to the last man in the Pacific War.

On August 15, 1943, the U.S. 7th Infantry Division (with the 87th Mountain Rgt, which later grew into the 10th Mountain Div) and the Canadian 13th Infantry Brigade along with the joint 1st Special Service Force, landed on Kiska as part of Operation Cottage and amazingly suffered over 300 casualties in the two-day operation, from friendly fire.
