Just a note on medieval armies: pretty much all of Europe that practiced feudal law had no standing, professional armies. Most "soldiers" were conscripts brought on by lower nobles obligated to provide them. Only mercenaries and nobles were truly professional soldiers, generally speaking.Jepix said:I just want to point out that I have a hard time seeing a medieval army that used "green" soldiers. More or less every respectable army during the middle ages uppholded a tradition of long training, even for crossbow-archers, which for the record were supperior in defending possitions like towers and fortresses.
The fact of the matter is that crossbows require less training then a longbow and packed a heftier punch*. Longbows were capable of greater range and faster firing rate but required many years of training**. And on the Pope banning crossbows, that only applied to their use against Christians. Crossbows became a common weapon for infantry during the crusades because Papal law dictated that they were permissible for use against Muslims.
*Any game (primarily tabletop RPGs) which allows use of poisoned crossbow bolts is ridiculous; the projectile doesn't remain in the body by-and-large thus negating the effects of the poison.
**English peasants, as has been mentioned, were required by law to train with the longbow. In fact, balls were outlawed as their recreational use was seen to detract from longbow training.
