Certainly the artistic/literary convention has been straight swords for Europeans & Westerners, curved swords for Mohammedans.
Let’s face it. The traitors in charge identify more with the Saracens than the Crusaders.
Swords may still be part of some military dress uniforms. The lack of green indicates the lack of ROP. I like the cannons. The Eagle standing on the bundle of sticks is also an American symbol. ROP blades are usually curved. I am also a fan of the Crusader garb also.
