Its a latin term,
'I am looking for the original Latin verse that loosely translates to
“Come home with your shield or on it.” The verse was more of a motto
amongst the Roman legions, supposedly a saying from a soldier’s mother
to her sons implying that you should win a battle (come home with your
shield) or die trying returning on your shield (the manner in which
fallen soldiers were returned home). The theory being that if you
came home without your shield, you had been a coward and fled the
battle—tossing your heavy shield aside such that you could run faster.'
