GPS down

Move low & off radar behind enemy lines over a satellite checked route. Move to the limit of radar contact with the central chopper at three or four equidistant points, rangefinder, need a compass heading N or NE & opposite, E or SE & opposite. Headings will be available even if it points in the wrong direction. Missile umbrella.

Hold the formation approaching in partial visual contact, but for obstacles. Get down & rotate if a jet comes to you, abort. Low flying will not bring a nuclear SAM to you because they will not see a group. Neither will the aircraft be able to see where you are without slowing & getting low - Minigun.

Choppers are still only in use 30% of time available. Practice. Also practice hitting an F-35 receiver with a laser attached to your minigun, needs computer compensation for speed & distance. Also helps hit Russian S type AA/nuclear missiles & warheads if flying away from targets to meet them head on.
