Abstract: The present invention generally relates to a military cannon as typically unted within the turret of a military armored vehicle such as an armored tank. My invention teaches method and apparatus for the catching and entrapping the stub case typically ejected from the breech of a military cannon after firing of an ammunition round. Subsequent to entrapment of the ejected stub case, the stub case catcher is raised to a preferred elevated angle simultaneously storing potential energy within a torsion bar which upon later release, ejects the entrapped stub case from the catcher and from the vehicle. By use of my invention and an automatic ammunition loader the crew requirements of such fighting vehicles may be reduced by eliminating the need for a human loader.
