About ammo system

[RTKMercurius]

Per unit, because knowing how to rid your enemy of ammo or numbers gave the knowledgeable player advantages over the other.... which is why it pays to study the game.

Also, armies in real life had reserve supplies and runners to fetch.... foot missiles and HA could go back to the rear to load up.... so per unit seems a respectable compromise (and who wouldn't jump off his horse to get more ammo, if you were safe to do so)....

"Crossbowmen, whether Genoese or otherwise, were essentially a static, or at least a defensive, form of infantry. King Philip's decision to send them forward against the English at Crécy, particularly as they were sent without their pavises, strongly suggests that the men in command of the French army during this battle had no real idea of how to use what were at that time regarded as the finest infantry in Christian Europe. The failure of the Genoese crossbowmen and their other infantry at Crécy was relatively brief and easily explained. They were used to forming part of disciplined and structured armies in which they would be closely supported by equally professional cavalry. Not surprisingly, therefore, the Genoese were not keen on advancing without proper preparation, without their pavises and without adequate reserves of ammunition from the supply waggons. Furthermore, they would be attacking at the end of a long day's march with the setting sun directly in their eyes. Their officers complained to the Count of Alençon, to whose battle or division they appear to have been attached, but were ignored."
