Just set me straight if I'm wrong but my usual opponent and I came across that, thoying around building fleets.
Fitting Ordnance Pods and Gunnery Team on the same ship, can you attack a ship once and squadrons within the same arc twice? Going with "prohibit overrides permit" we'd say no, since Ordnance Pods only allows an attack from the same hullzone, whereas Gunnery Team explicitely forbids attacking the same target twice during the activation.
Are we correct?
Because in that case the third attack would only be useful from another hullzone. And even then you could only attack squads you haven't already attacked.
