A military mascot, also known as a ceremonial pet or regimental mascot, is a pet animal maintained by a military unit as a mascot for ceremonial purposes and/or as an emblem of that unit. It differs from a military animal in that it is not employed for use directly in warfare as a weapon or for transport.
