The 2/10th was originally mobilised as bicycle infantry, but never served in this role. It was the only second-line battalion of the regiment to be sent overseas, moving to Archangel in August 1918, and serving in the North Russia Campaign until June 1919, when it returned to Scotland to disband. The remaining battalions all remained in the UK on Home Service, and did not see active duty. However, six saw significant periods of service in Ireland, where they served as garrison units, and were often involved in local security – armed patrols, mobile columns to 'show the flag', and the like.
