Welcome to Librarium Online!
I'm running a Battlewagon w/ a Killakannon w/ Lootas riding in it. Can I fire the Lootas as well as the Killakannon (since it's ordinance)?
Battlewagons are opened topped vehicles unles you give them the ard case so all the lootas can fire if you don't move and you can fire the kannon, but they have to target the same thing.
Blu-saber is right on all counts besides one: they do not have to target the same unit. The lootas and battlewagon can freely target separate units.

Yay grax! I was waiting for you to answer that....
