Just for sake of comparison, here is the formation badge of the old Canadian Special Service Force
, which was a descendant of the WWII "!st SSF" (aka the Devil's Brigade). The logo is a winged sword with the motto "OSONS" (We dare).
BTW, pers I know from the SSF tell me the motto stood for "Oral Sex Or No Sex"
\"What are you talking about? One, two, three, fo-- oh, crap.\"
