"The Lone Sentry" has an interesting page on the 50mm PAK38

I was looking for more information about the 50mm PAK38 anti-tank gun. "The Lone Sentry" has a good page that includes information from an Intelligence Bulletin from February 1943. One piece of information that I had not realized, but which makes sense, is that hits on "the junction of the turret and hull" would fuse the metal and jam the turret.
