The regiment is also unusual in having the word Royal appear twice in its name. It gained the first "Royal" in 1804 when it was known as the Monmouth and Brecon Militia. The second was acquired in 1877 when the regiment transferred from an infantry unit into a Special Reserve section of the expanding Royal Engineers.[1]

On 1 April 1967, the existing regiment absorbed 43rd Wessex Division RE (TA), 48 South Midland Division RE (TA) and 53rd Welsh Division RE (TA).[2]


The Regimental Headquarters (RHQ) are at Monmouth Castle in Monmouth and its sub-units are:[3]

- 100 Field Squadron (Militia) based in Cwmbran, Cardiff and Bristol.

- 108 (Welsh) Field Squadron (recently reformed after disbandment in 2014) based in Swansea

- 225 Field Squadron (Militia) based in Birmingham, Cannock and Stoke-on-Trent (which used to be the home of 125 Field Squadron, 75 Engr Regt).

- Jersey Field Squadron (Royal Militia of the Island of Jersey), based in Jersey and Guernsey (but under operational control of 25 (Close Support) Engineer Group.[4]
