I grabbed the Tau Empire 5th edition
FAQ off the
GW site, and was confused by the tau drone query:
Q. If a unit with advanced stabilization systems also has Marker Drones, can the drones remain stationary to fire their markerlights while the Battlesuits move using their advanced stabilization systems?
A. No, since models in the unit moved, the drones, which do not have a stabilization system, may not fire a heavy weapon.
I was under the impression (reading my 5th ed book) that jump infantry models with jet packs (i.e. battlesuits and any drones that accompany them) get the relentless special rule, which allows moving models to fire rapid fire and heavy weapons as if stationary... so why this ruling?
Edit: Okay, I missed the A.S.S. part (hrm... I don't think they were really looking to acronyms when making that up), and realize that primarily the systems go with broadsides, which are infantry, not jump jet infantry... and I doubt anyone is crazy enough to put the system on a normal battlesuit, so the question is kinda moot
