ロングボウ
Swords used were a short infantry weapon like the Roman gladius and the Sassanid long sword. Both were worn hung from a baldric. Bows were about two meters long when unbraced, about the same size as the famous English longbow, with a maximum range of about 150 meters. Early Muslim archers were infantry archers who proved very effective against the opposing cavalry. The Rashidun troops at the Sassanid Persian front were lightly armored compared to those deployed at the Byzantine front
