The M100 is a light one man walker and my assumption is that they are available to British forces in any Weird War list. This example is armed with a gatling gun, a bazooka (rotary mag) and an assault rifle (slightly over powered if you ask me). I would class it as having a twin HMG, a bazooka and an assault rifle. Single crew so only one weapon at a time. The assault rifle is probably used to scratch colleagues' backs.
Now, the question is, where do you put the decals?
I am putting recognition marks on the shoulder (left side) or the gun mount (right side).
It is where to put the tactical sign and perhaps a division insignia?
The following have been put together electronically (the tactical sign is from the Warlord Games Guards Armoured Division decal set).
First, on the plastron (chest plate).
