Medal deemed unlawful as it is too "Christian"
There's a precedent for this. The Imperial Russian Order of St George, their highest military award, depicted St George (oddly enough!), a Christian warrior saint. Because there were many Muslims in the Russian army from the Southern fringes of the empire there was a Muslim version of the insignia which replaced St George with the imperial eagle. Many Muslim recipients rejected their own version, preferring the one showing a brave warrior rather than a black bird.
