Drop Pods  
Drop Pods allow ground units to make air drops. A unit must begin its turn in a friendly base or airbase in order to make an airdrop. Airdrops may be made into any empty square within 8 squares (unless your faction has the technology necessary to make Orbital Insertions, in which case units may be dropped anywhere on the planet).

Drop Pod units may move after an airdrop, but if they attack a 50% combat penalty applies.
