Hadn't seen one yet. APCR assume was left out for it's scarcity (but should be a very simple mod) . HEAT probably isn't there for it's simple lack of usefulness; the standard round PzGr. 39/43 had nearly double the velocity and much better penetration performance even at 2 miles. HEAT rounds tended to be issued for weapons where they were the superior option, at least at longer ranges or outright in the case of the low velocity weapons. In this case it was inferior in all aspects.

Thanks yeah I have been doing some research and they didn’t really have a heat round but the APCR in that caliber was quite useful I def would love to see it appear at some point
