Artillero is a "Luchador enmascarado", or masked professional wrestler while Súper Comando worked as an "enmascarado" until December 25, 2015.  Artillero's real name is not a matter of public record, as is often the case with masked wrestlers in Mexico where their private lives are kept a secret from the wrestling fans.  Artillero and Super Comando are the brothers of CMLL low card wrestler Bengala, although it is not openly acknowledged by CMLL.  The two use a military theme, reflected in their ring gear, mask and trunks which is at least partially camouflage.
