The Mamiya RB67 is a Beast
At the end of the Second World War, the cover of an American comic depicted a female Army photographer named Linda Lens hitting a German soldier knock out with a Kodak Medalist on a strap.
Impressive for sure but to make a real impression (on a soldier’s helmet or elsewhere), I’d advise the Mamiya RB67.
