[@Commodore]Basically, the only specifics for vehicles should be some sort of European Civilian vehicle appropriate to the time period, modified for a military purpose, which usually entails either the addition of a machine gun, armor plating, or sometimes both. Most every vehicle used by the Blackshirts is a civilian vehicle, confiscated and retrofitted with military upgrades, so as far as what vehicle it is specifically, you have a bit of free reign there.
EDIT: also, as far as standard-issue gear for a Vehicle Driver, use the cavalry carbine found in the intro post.
