Minimum no. of men in siege weapons

What's the minimum number of men to operate catapults, culverins, mangonels etc?

Answers on a postcard please...

3-4 I think, although this may depend on unit type (could be 2 for ballista, and 5-6 for trebuchet). This is what I remember from battles. Anyone with hard data?

It says under ProjectileStats.txt I don't have one to look at ATM. But it's under the column (in GnomeEditor) MinSoldiers or something like that. As you have less and less soldiers manning the weapon, it gets less and less effective. That's why a unit of 2 manning a ballista will reload very slowly compared to a unit of 12.

projectilestats.txt has 2 columns for siege weapons, minCrew and numSoldiers. According to the comments, minCrew is the minimum number of crewmen necessary to fire the weapon, numSoldiers is the number needed to fire it at full effectiveness. I assume this means that as the crew drops below numSoldiers, the fire rate/accuracy drops, until the crew goes below minCrew, in which case it can't fire at all.

Values in VI's version of projectilestats.txt (minCrew,numSoldiers)
ballista - 2,6
catapult - 3,6
trebuchet - 6,12
mangonel - 6,12
bombard - 6,12
culverin - 4,10
demi-culverin - 8,12
siege cannon - 8,12
demi-cannon - 8,12
mortar - 4,6
serpentine - 4,8
organ gun - 4,8

Cheers!
