Remained as a prototype , only five copies were built. the only flights they do serve to develop the technology in future versions of the AH-64 and subsequent programs of helicopter gunships and nothing else.
if arma3 simulates a 3rd world war, I think it would be good to involve different countries but with their own respective weapons. Do not focus on U.S. and Russian weapons and leave a few crumbs, as a few guns, to other countries. Remember that the major weapons manufacturers are first the Russians and Americans 2nd, 3rd French and the Germans 4th, the British 5th and the Ukraine, Canada, the Netherlands, Italy ... etc
So there is just to add in ARMA3 weapons that already exist and focus on different countries so that players around the world can feel flattered ,concerned and have the pleasure of playing with their weapons, there's nothing else better to attract the customer ,and with no need to add hypothetical prototypes.
For instance,as being a French, there is nothing more fun than to be in control of a Leclerc tank, a Rafale, a tiger, a VBCI or shoot with a FAMAS or a PGM Hecate II: protest:
Same for the German with a Leopard 2A6, a Puma, a tiger ...
or an Englishman to fly a Typhoon ...
or with a Swedish CV 90 ...
or with a italian Ariete tank...
To make it short, let's think a little to everyone, Russian and american weapons are great, but all the time it is boring.
I hope you will think about all this and thank you for this excellent game.
sincerely yours
