Vehicle, weapon mount, siege engine and sniping duo

[Waldham]

Hello, is it possible to install a weapon mount on any vehicle ?

Is it possible to install a siege engine on a weapon mount ?

Is it possible to use duo sniping with a sniping duo archetype ?

Are Siege engines in the bow or firearm groups ?

Thanks for your future answer.

Gonna leave weapon mounts for later, since it is possible for siege weapons to be mounted any vehicles and the rules refer to that, but that doesn't imply mounting any siege weapon on any vehicle. A chariot and a galleon are not similar situations.

Siege weapons are not in any weapon group.

Abilities that affect attacks with a normal weapon only ever affect siege weapons by a GM decision to allow that specific benefit to affect that specific siege weapon.

Special attack actions for normal weapons cannot be used with siege weapons.
