Stegadons carry one giant bow into battle, while Ancient Stegadons carry two giant blowpipes.

Howdah weapons can be fired even if the beast moves, but not if it marches. It takes two crew to fire a giant bow, or one for each giant blowpipe (so two Skinks can't throw javelins if the weapons are being fired). Remember that the Stegadon is a large target, so the crew may shoot over normal-sized units.
