Once you have a basic Rifle Company, converting them to being an Armored Rifle Company is fairly easy: just add half-tracks...lots of half-tracks!
This is probably the most powerful single force you can encounter in WW2, with a plethora of MMGs, HMGs and armored support options.
All the figures below are Battlefront, apart from a couple of the Big Men who are from Peter Pig, Essex etc. The basic infantry are painted by undercoating the figures in white, washing them with a dark brown ink, and then highlighting in the appropriate colour.
