I suggest we use a picture of a tank destroyer. tank destroyers have been misidentified as tanks be military officers who then use them strategically/tactically like tanks. it doesn't always end that well well.
There are two different things this article address:
Things that are not a tank being called a tank.
Anachronistic tanks being used instead of historically correct tanks.
Some of the Wall of Text could probably be moved to an Anaylsis page.
