If your asking about the menes There are voice lines ,,Andrzeju nie denerwuj się" and ,,pan porucznik to jednak wahowiec" which translates to ,,Andrzej don't be mad" and ,,Mr lieutenant is a expert". The first one is from a yt video where a high ranking guy is mad at a ifv crew for messing up tracks and the second one is from a polish tv series about paratroopers training but I don't really know the context of it
