Did units in WWII regularly resupply in action? Or did they pull out of the line to do it?
Good question, and I am not really sure of the answer. It’s probably a question that relies a lot on context. I’m sure others can give you a more detailed answer.
In terms of the units I field, they are integral to the formations represented, being supply vehicles that would have accompanied that particular formation and remained close by. This is about immediately available supply, not supply dumps or anything like that.
