The MH-9 and AH-9 (which are the wrong designations for the Little Bird, if it's supposed to be the same as the extant helicopter by the name Little Bird. Should be MH-6 and AH-6) are not equipped with radar warning for incoming missiles, IR jamming and flare dispensers. These are standard defensive equipment for all AH-6J and MH-6J's.
The Ka-60 does have flares, but I'm unsure whether they have incoming missile warnings.
These are simple features that all air vehicles have, I don't see why the Little Bird is left out unless it's some attempt at "balancing" its high maneuverability. This would be unacceptable for Arma. If it's just an omission due to not yet being implemented, colour me satisfied.
Thanks for reading.
