Carthaginian Sacred Band Infantry
The Sacred Band is the elite infantry of any Carthaginian army and can be relied upon to do their duty to the end. They are equipped and organised in the same fashion as the Greek hoplites, with long spears, large shields, breastplates and helmets, and they can use phalanx tactics. This is a style of warmaking that has proved its worth over the centuries.
They are drawn from the social elite of Carthage, men of noble and wealthy birth and their loyalty is exemplary. The original purpose of the Sacred Band was to act as an officer corps for the Carthaginian army and an elite force, and to put Carthage above any local loyalties. Opponents have learned that these men are formidable in battle, a linchpin for the entire Carthaginian army
