All operators in a Cimmerian re-enactment must be at least 18 years of age to engage in combat.
California law requires that you be at least 18 years of age to purchase an Airsoft weapon, so the Cimmerians cannot encourage otherwise.
Also, because Cimmerian re-enactments are conducted on private and public lands, each operator must be legally responsible and liable for his or her own safety, and minors cannot be accommodated.
