I 've noticed that captured weapons such as BAR, Bazookas etc fail to appear in the hands of PE infantry... And if my memory serves me well this was happening before 2.602 and even without EF installed. Sometimes i remember that if i instead of selecting a bunch of infantry and order them to capture such a weapon, selecting a single squad though would have worked sometimes.
I don't know maybe it's only happening on games that i've played or it happens to everybody...I would have posted some pics but it's to easy to test it.
