There are 17 regular infantry regiments in the British Army. Eight of them are single battalion. Five of those eight are Guards units. Since the Second World War all the regiments but the five Guards units have been renamed and subject to amalgamation. Many long-storied units have lost their identities. Efficiency and flexibility has been the reasons given for axing many of the great regimental names to create the new multi-battalion regiments. I guess Her Majesty's Foot Guards must already have been super-duper efficient and flexible. One of the features of the super-regiments is it is easier to axe a battalion once in a while. In recent years, the Argyll and Sutherland Highlanders has been reduced to one company and the Royal Regiment of Fusiliers cut to one battalion. But Whitehall is shying away from creating a unit simply known as The Foot Guards and sneakily axing a battalion. One of the problems is that three of the five Guards regiments are named in honour of constituent parts of the United Kingdom. Though, it must be hard to justify the Irish Guards when the part of that island which is still British territory is pretty small. It used to be the most junior regiment would be the first to be disbanded. In this case, that would be the Welsh Guards, formed 1915.  But let's make ending the Guards' immunity from the painful reorganization process the rest of the British Army has undergone a little gentler. How about the regiment with the fewest officers from the area is is supposedly traditionally recruits from gets the axe? But I don't think I'll hold my breath waiting for that to happen.
