A well trained bowman can get off projectiles that kill a man and pierce armor. Coupled with the artillery, this is a very easy win for the medieval times. The men at arms and cavalry could be useful for Zulu-tactics. The dragon would be overkill.
The humvees could rsck up some kills but that is where i leave the luck factor. It really depends on the effectiveness of the humvees.
How far can a bowman shoot? 200 Meters? 300 Meters? And only on ground targets surely. While with an M4 you can (relatively) easily shoot a human sized target at 500m - 600 m. Against a tight formation it would be a massacre.
The medieval site is screwed. Good game, well played, no rematch.
A Ballista can probably shoot up to 500 Meters as well, but only against ground targets.
