There doesn't appear to be any de-icing systems on the leading edges (and by inference the prop). If I am correct, isn't that going to somewhat limit the operational scope?
Also the engine cooling air-intake is behind the gear - I would have thought not ideal for contaminated runway operations.
What sort of training do the gunner operators have before flying them? I'd have thought they would need a reasonable depth of aviation experience to operate them competently under IFR and in all weather, let alone in combat airspace.
