Will NOE be possible in-game? One of the STEAM achievements for Steel Alcimus 2 is called Nape-of-the-earth, but such a maneuver is impossible in Steel Alcimus 2 as the playfield is flat.

NOE is possible by carefully controlling collective and cyclic to maintain lowest radar altitude, and it's important for your survival especially against AA units.
In the next patch AI helicopters will be able to perfrom NOE against AA units as well, and Shilkas' radar guidance will be less accurate when their target is lower than 60 meters, which is caused by false returns from ground clutter.
