Having reached the point where I need to apply the division insignia, I had to actually decide which division the chaps would be part of. I live in Rugby so decided to use the 48th (South Midland) Division, making the soldiers part of the 8th Battalion Royal Warwickshire Regiment, 143rd Infantry Brigade. This was a Territorial Army brigade.

With that established, my Vickers Mark VI and recce Universal Carrier will belong to 1st Lothian and Border Horse, a yeomanry regiment, the 25mm Hotchkiss ATG will be 53rd (Worcestershire Yeomanry) Anti-Tank Regiment RA, and the artillery support (and therefore the Forward Artillery Observer) will be courtesy of the 68th (South Midland) Field Regiment RA.

It doesn't really matter which exact units they all belong to, of course, but it is nice to be able to put them within a hierarchical context.
