Ability: Attacks air units
Cost: 1

Doubles combat advantage when attacking other air units in flight but gets -50% penalty against ground or sea units. Air-to-air combat is resovled by comparing attack factors (ignoring armor). Note that even ground and sea units can be equipped with the SAM missiles to confer this ability.

Ability: Attack from ship

Amphibious Pods allow a ground unit to attack directly from a sea square when disembarking from a transport. Units with Amphibious Pods may also move and attack across the channels between Sea Bases and continents.
