Denmark   Danish Army enlisted man’s kepi (M15) With WWI underway to the south of neutral Denmark, the Army decided to introduce a better-camouflaged uniform in 1915. The light gray was, in fact, a poorly-chosen color and was quickly deemed a temporary measure. Nevertheless, the gray uniform continued to be used up until 1939, although it was officially supplanted by the olive-green 1923 uniform. The “2” on the front indicates that this soldier was a member of the 2nd Battalion.
