This thread reminded me of this...

I started it back around 2001-ish and, as you can see, haven't quite finished it yet, although the main military comparisons are there.
In my humble and obviously biased opinion, it's the best "go-to" chart there is (although I don't claim that there's no typos, lol). I might finish off the Soviet comparison this weekend (I have the data, just haven't plugged it in yet).
EDIT: I should stress that my sources are all original WWII documents from ~1942. My primary sources:
-for US information: USN Rear Admiral J.W. Bunkley's well known "Military and Naval Recognition Book" 3rd Edition 1942 and the US War Department's "Handbook on German Military Forces", 1944.
-for Kriegsmarine information: Various Kriegsamrine recruitment pamphletts
-for Commonwealth information: "Ranks and Badges in the Australian and USA Navy Army and the RAAF and Auxiliaries", 1943
No post war "memories" or revisionism.
