Brace for impact! Parthian cataphracts overrun a Roman formation
Wait, why are there spikes on the inside of the shields? Are they stupid?
Arrows embedded in the shields - the Parthians were notoriously good horse archers, and by some accounts, their arrows punched right through Roman shields, at least some of the time!
Ah, I see. Love the attention to detail, like the soldier scratching his back in the middle of the frame!
