The warrior caste was lower station within the Geonosian aristocracy. Members of the warrior caste were winged and divided into two sub-categories - the elite and the regulars. They matured quickly, achieving maturity at age six at which point they were battle-ready. The Geonosian Hive Army was consistuted of the warrior caste and dealt with internal struggles inside the hives, as well as to protect it from foreign threats.
The regulars were bred for simple defense and security. They lacked a high level of intelligence and were equipped with simple static pikes and sonic blasters. They wore no protective armor of any kind but were able to use their large numbers and ability to fly to their advantage. The picadors used in the Petranaki execution arena were drawn from the regulars of the warrior caste. They rode orray mounts and carried force pikes.
The elite warriors were more intelligent than their regular counterparts. They were often enhanced with cybernetics and given more powerful weaponry, such as elite beam weapons. The elite also differed physically from regulars in that they had an extra pair of walking legs and longer abdomens.
