Thundering and fat and beauty can mean only one thing... the lady I was missing when I commented on the Mustang, even though she's a fine lass too... my beloved Jug!
But a guy with a Kittah? I would say that it's two things. Kittah is of course the long-awaited Jagdpanther, but the guy... well, American tanks were named after guys, so I'll take a guess and say M36 Jackson. Would fit since they're both tank destroyers.
This leaves only the "accurate punch"... I'll guess that it's a long-reaching fist, ie. Panzerfaust 60 or 100.
