Is Power of the Machine Spirit stackable?

[tegonzalo]

I've recently discovered the wonders of techpriests engineseers for IG, and how the can give out PoMS to nearby tanks. This solves my problem of ordnance in Leman Russes, allowing to shoot the hull lascannon at full BS (confirmed by the recent FAQs). I was wondering though, if I field more than one techpriest, could I stack PoMS on the same Russ, thus allowing me to also shoot the sponsors at full BS? Couldn't find an answer to this anywhere, any ideas?

I could be wrong, but I don't think they stack. The way the rule is worded in the rulebook is that you can fire one additional weapon at a full bs. But someone even more knowledgeable about the rules could maybe clarify.

You're definitely right. As a matter of fact I just found a short line in page 156 of the rules that says that unless specifically stated, a model cannot gain the benefits of a special rule more than once. So despite the wording of PoMS and the AM codex being ambiguous, at least in my opinion, it doesn't specifically say that it can stack.
