If you purchased the SSU Specialists pack in the last few months you may have noticed that the Observers have no guns. Also you may have noticed that FFG has quietly re-released the SSU Specialist Pack with newly armed Observers. Apparently the Observers lack of armament was a manufacturing error.
Link to the release announcement: Snipers, Heavy Walkers, and Command Vehicles.
