I know it's a bug right now that relic needs to fix, but I don't think Conscripts should be able to re-man heavy weapons or pick up weapons left behind for balance reasons. But when it comes to any other unit taking up a population point, they should be able to re-man equipment.
It could be reasoned in game that "due to their poor training, they don't have time to figure out the weapons on the field".
Let me know what you think.
EDIT: I was just able to pick up a panzerschrek with one of my Red Banner units. Is this possible? I thought this was still bugged.
