Maximum range airborne movement is same with air mobile movement?
Airborne unit from PRC holdingbox can only move to Hex map and Penghu land area. Is it correct?
There's no range for Airborne Movement, per se. There are simply limitations on where such movement may occur. You are correct that PRC Airborne Movement may only occur between the PRC Holding Box and Penghu and the Operational (hex) map.
