The present invention relates to a hand grenade comprising a main body (10), an actuator (14) releasably fixed to the main body (10), an actuator-ejection mechanism, and a charge to be released, which includes an automatic-identification device (34) embedded in the actuator. The invention further relates to a grenade actuator of the EOT-type (Espoleta de Ogiva de Tempo, time fuse point), which comprises an automatic-identification device (34) embedded therein. The present invention can also materialize in the form of a method of manufacturing a hand-grenade actuator, according to which it is provided a housing for an automatic-identification device in the actuator body. Indeed, the method of manufacturing the actuator further includes providing said housing with a cylindrical shape and then inserting an equally cylindrical automatic-identification device into said housing.
