Everyone knows that Jews served in the draft military of WWII, in fact 1 out of 3 Dentists and Doctors in the military were Jewish in WWII.

WWII with it’s massive draft where all branches drafted and the Army reached 97% draftees is definitely well known by everyone as having Jews well represented in it.
