A quite long time ago I read somewhere that a company of shermans used to paint red and white dragon faces on the frontal armor of their tanks to scare the hell out of the chinese (I think it was at korea, but can be during WWII, then make that japanese

).
Now I'm quite interested in the company, and the captain who commanded them but I don't remember where did I read it and can't find it anywhere using google...
so...does anyone know it?.
BTW if the exact subtype of shermans used is known, I'm also interested in it.+
thanks in advance.
