NAPE is where a helicopter uses peaks and troughs in the terrain to move into a suitable firing position without been seen by the defender, in the screenie 3 soviet hind gunships head south down the riverbed before heading NW and popping out approx.. 1km from the MANPAD section. The MANPAD was then forced to engage 3 helicopters while being within their engagement range...often not good for the MANPAD
BTW, I was the British and the Soviet was the AI......AI making NAPE movements [X(] cannot think if I've seen a AI do that
