Well, I don't have access to any military, but why would they say that? To my knowledge the US has abandoned the development of their advanced attack helicopters, and it's not because the current ones are flawless. Their Apaches are very vulnerable in a modern threat environment. The Russians seem to have lots of inventory, who knows what they are thinking. Even Perun states a lot of Russian tactics and doctrine seem very old fashioned, using helicopters in a way that doesn't seem particularly cost effective (e.g. in roles better served by artillery). As for China, I haven't the faintest idea. What's their use of attack helicopters?
