Morale

Morale reflects the training and experience of your military units.

Levels
A unit receives a +12.5% combat bonus for each morale level. Morale plays a particularly important role in psi combat, and in combat between probe teams, since no weapon and armor values are considered in those cases. Morale levels are:
 * Very Green
 * Green
 * Disciplined
 * Hardened
 * Veteran
 * Commando
 * Elite

Elite units receive a special bonus--an additional move each turn.

Alien units such as Mind Worms have life cycles which correspond to morale levels. Alien units are not affected by Command Centers and military facilities, but their life cycle levels can be improved by building Biology Labs and other similar facilities. The transport capacity of an Isle of the Deep is determined by its life cycle level: one unit for each level.

Training
New units typically begin with Green morale, though this may be higher or lower depending on your social engineering morale setting. A new unit's morale can also be increased if a base has a Command Center or other related facility.

A unit victorious in combat will often receive a morale upgrade (the lower its morale level, the more likely an upgrade).

A unit with a "+" sign after its morale possesses a combat bonus from its location in a base with a Children's Creche.
