1st Battalion, Mercian Regiment (Cheshires) - Light Infantry based at Catterick
2nd Battalion, Mercian Regiment (Worcesters and Foresters) - Light Infantry based at Holywood, Northern Ireland
3rd Battalion, Mercian Regiment (Staffords) - Armoured Infantry based at Fallingbostel (although it will move there in 2009 from Tidworth).
4th Battalion (V), Mercian Regiment - A T.A battalion created from the West Midlands Regiment
It is called the Mercian Regiment as it is generally located within the ancient English kingdom of Mercia. It was expected that the regiment's cap badge would have be a double headed Mercian Eagle with Saxon crown, but this has been rejected by the Army Board due to its strong Territorial Army connection. However, this badge has been displayed on the regiment's website since early 2006, suggesting that it has been adopted unless/until a new design is approved.
