ABSTRACT:
A practice projectile allows for the release of flame or smoke and bang upon impact to simulate a successful deployment of the tactical cartridge. The practice projectile includes three main components: a center vent tube, a plurality of vent holes, and a plurality of vent plugs. The center vent tube compensates for the physical properties of the tactical mortar cartridge and provides a passage for an efficient release of smoke upon a fuze function. The vent holes are positioned at the rear end of the projectile body to sufficiently release pressure, flame and smoke upon a fuze function. The vent plugs seal the vent holes to protect the interior of the projectile during storage, handling, and launching.
