Option 31

Destroying and Scrapping Units
Disbanding:

Every turn during the Reinforcement Stage, each active major power may disband one of its naval or air units that is located in a home country factory hex; if it does so, and the scrapped unit costs 2 or more build points (2nd cycle cost for naval units), place 1 build point in the hex in which the unit was scrapped.
 * If an air unit is disbanded, it is scrapped.
 * If Option 46 (Pilots) is in use, increase the major power's number of available pilots by 1.
 * If a naval unit is disbanded, it is placed in the construction pool.
