As the Roman Empire spread, so did their weapons and tactics. The Angon was a Germanic version of one of the most famous Roman weapons, the Pilum. It was constructed of a wooden shaft surmounted with a long metal tip that had a barbed head on the end. Being a type of javelin, it was thrown at an advancing enemy to break their ranks, immobilize their shields, or obviously, harm them. It had a maximum effective range of 40-50 feet.
