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!
Well I haven't got lots of half-tracks, at least not yet, so most of the infantry for the core Armored Rifle force are on foot. That aside, 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.
