What on earth do you need another sensor and weapons platform on the battlefield for when you have the Apache?
The the US Army is mistaken in calling for a 4/1 ratio of OAH to AH helicopters.
(as the DoD cancelled its Armed Reconnaissance Helicopter in Oct 08).
That's going to get un-cancelled. The Army can't decide which helicopters to get, or what the ratio of manned to unmanned Observation Attack platforms should be. The manned choice or choices is probably going to be something more like a Lynx than a Kiowa, meaning more than two seats. However, Armed Observation will remain a distinctly different role from squad-sized assault transport.
