Craft

Craft is an expendable, renewable "resource" used by various units in the game, appearing as a small blue bar above a unit's hit points bar. Craft is somewhat similar to the concept of mana, magic points (MP) or spell points (SP) employed by many fantasy-themed games.

Craft regenerates automatically at a set rate, which can be increased by researching Strategy technologies at Forts.

Totalitarian Patriots' (Monarch, Despot, Comrade) craft can be increased by 1000 for each Smelter researches: Forge, Supply, Logistics.

Spies, Generals, Patriots, and all Scouts require Craft to use their special abilities.

Spies: Counterintelligence, Bribe and Informer
Patriots/Generals: Forced March, Entrenchment, Create Decoys and Ambush
Scouts: Counterintelligence, Sniper and Sabotage

Craft is also used to simulate fuel capacity of fighters and bombers, which in turn is used to limit the operation range of these units; each aircraft uses up 1 Craft per frame (or 15 Craft per second).
