Abstract: The present invention provides for a network connected training projectile that provides user feedback and is used to determine a trainee's proximity to an appropriately sized explosive blast zone. The invention solves the unmet need for close combat indirect fire (mortars and grenade launchers), or hand grenades which can be safely used in live training exercises. The invention further solves that such use is interactive with the training environment providing the ability to calculate the extent personnel participating in a training exercise would be affected by the training grenade in a real-life scenario. The invention further determines mortality of participants who would have been affected by the training grenade.
