Hi all, a couple of q's

The entry for the mordor catapult says it always uses the rule for volley fire giving it a range of 18" to 96". In the Hobbit rulebook it states that all siege weapons have a range of 48" and catapults may volley fire. Which rule should we use? The idea of a catapult with no minimum range gives me chills

The Hobbit sourcebook states that engineer captains are derived from "a captain taken from the relevant source list". Mordor has a lot of generic captains to choose from. Could I take a Black Guard captain, morannon orc captain or uruk hai captain? Am I able to spend 5pts in order to give them a bow, to bring it to 70pts?

Are siege weapons themselves generally counted as siege targets in games? Also, would shots scattered to them give a str 5/6 hit to all models in 2 inches? It seems sad that a bang-on hit on a catapult will give a huge hit to all crew around it. Even if it doesn't outright kill it, it renders it useless.

Hope you guys can help, thanks heaps

Catapult can't target lower than 18". Use the rull for catapult.
I don't remember if you can take another captain from an ork one.
I'm not use to siege battle I don't know for the last question sorry.
Have fun playing Lotr SBG
