[split] Phalanx warfare: use of the spear

[Dan Howard]

Dan: Tube and yoke armor if made from leather would be not that great at protecting against spear thrusts anyway ( do i remember it right - Dr Williams managed to penetrate hardened leather with just 30 joules? )

Williams tested 5mm of cuirbouilli. On the battlefield, this armour was worn over the top of mail, not by itself. Standalone leather armour was multi layered and usually 1-2 cm thick.
