Switzerland
 
Swiss Militia kepi
Switzerland doesnít have a standing army, rather, each male of military age is a member of the militia. They keep their weapons and uniforms at home, which allows the country to mobilize on very short notice. This particular cap has the insignia of a sergeant majoróidentical to the U.S. Air Force arm chevrons. Alas, I donít know all that much about Swiss uniforms so if you have anything to add, please let me know! I suspect the badge is a later add-on.
