France: Gendarmes
-They kept som military duties. Like, say, in case of war protecting sensible sites. For this specialized units are equipped with light armament like light armored vehicles. They also protect official buildings, so actually you can see them in Paris (actually police doesn't wear kepis anymore in France, so now any "police" officer you'll see with a kepi is actually a gendarme). The french "republican guard" (ceremonial unit wearing fancy 19th century uniforms and riding horses) are gendarmes too. They also guard embassies on foreign soil, are in charge of training/ replace the local police during peacekeeping operations, etc...
