Gunner supressing fire rule

New to gunner faction. Not sure how how to use it and i cant find ant info on it.

I haven’t watched this one specifically but, this guy does pretty good overviews of the various factions and new releases/rules.

As far as the “Supressing Fire” rule, as I understand it any models withing aura range gain the ranged attack quick action (crosshairs icon), allowing them to use action points to make ranged attacks.
The caveat with Gunners factions is that their abilities only work if someone of higher rank is within LOS and Presence range (telecom icon). Don’t miss out that they all have “Ruthless” and “Orders” abilities as well (mentioned on their reference card).
