Many famous comic book characters were made during the world wars and it was shown fighting beside troops in the original comics. Wonder-Woman is the best fighter in DC Comics, Batman has already confirmed this “If Wonder-Woman were to ever go berserk the only super hero capable of stopping her is Superman”. Deathstroke, Black Canary etc are all good but Wonder-Woman is the best fighter and she doesn’t even have to rely on her strength she’s a trained warrior. Batman also proved to Superman that she’s faster than him in combat. Superman is faster in raw speed but Diana told him she’s faster in combat due to her muscle memory from her warrior upbringing another claim Batman backed. So whether superman is your favorite, or because Wonder-Woman is a female or whatever other reason you refuse to accept it the fact is she’s the best fighter in DC Comics.
