Alright then. Can I be in the Royal Engineers?

I sent you a PM regarding Combat Engineers and those Engineer Units assigned to the UK 1st Armour Division. I list the Regiments and the Brigades they support. For my own sanity I post the fact that they are Battalion strength. In my world, a Regiment is the size of three battalions. France and UK have smaller regiments than the US. Please pardon me.

21 Engineer Regiment (Battalion strength) supports 4 Mech Brigade
32 Engineer Regiment (Battalion Strength) supports 7 Armour Brigade
35 Engineer Regiment (Battalion Strength) supports 20 Armour Brigade
