The country was officially called Germany (original "Deutsches Reich/Großdeutsches Reich") at that point. In English it was called "Nazi Germany" to represent Germany over the '33-'45 period but that sounds as accurate as calling US now "Republican USA" (insert ideology here). Nazism is an ideology and it was never an official part of the country's name. People use it to easily distinguish periods but it doesn't make the naming any more accurate. So I'd guess "German Army", "German Navy", "German Air Force" if you want to use translated names. Otherwise "Heer", "Kriegsmarine", "Luftwaffe" if you want the originals. Or generically "Wehrmacht". Nitpicking, I know, but there is some substance to the point.
