A diversionary device trigger mechanism is provided that can be repeatedly used, and which allows a primer or blank to be discharged in two different ways. The device includes a main body with a number of other components secured to the main body about an upper chamber and a lower chamber. A firing pin, a ball bearing, an anvil, a top retaining cap, and a plunger are secured about the upper chamber. A blank carrier, a primer or blank, and a carrier receiver are secured about the lower chamber. In the first way, the ball bearing can be displaced relative to the main body, such as by throwing the device towards a surface. In the second way, the plunger can be pushed down relative to the main body. If either of these occur, the firing pin to be moved downwardly to pierce and set off the primer or blank.

Provided is a non-pyro cartridge for military training devices. The cartridge has a refillable compressed gas compartment fitted with a refill valve, which allows for quick reuse of the cartridge. The cartridge further has a blast compartment that receive a rush of compressed air from the gas compartment when the cartridge is triggered/detonated. Also provided is an activation device for the cartridge. The cartridge and activation device can generate physical and digital effects on the battlefield that safely and realistically simulate anti-tank weapon signatures, mortar weapon signatures, landmines signatures, improvised explosive device weapon signatures, artillery point of impact signatures, hand grenade signatures, weapon impact signatures on vehicles, weapon impact signatures on buildings, multiple types of battlefield effects, weapon signatures, impact signatures with a single device type.

A method and apparatus for simulating a hand grenade in a training environment. The hand grenade includes dead reckoning to determine location after leaving a thrower. By knowing a location of the thrower and subsequent path after leaving the thrower, the explosion location and simulated damage to targets can be determined. The simulation can determine the effect of obstructions between the explosion location and nearby targets.

In some examples, a charge holder for a grenade has an envelope made from one or more layers of a sheet material to define an interior volume to receive a charge having a charge volume less than or equal to the interior volume and a neck configured to connect to a flashbang grenade body, wherein a ratio of a charge volume of the interior volume to an envelope material volume is about 5.0 or greater.

A digitally controlled hand-tossable explosive delivery receptacle comprises a ruggedized reusable compartment enclosing a digital circuit and a disposable cartridge holding one or more explosive chemical agents and a primer. The disposable cartridge is configured to be mounted to the ruggedized reusable cartridge, and a high-strength bulkhead incorporated into the reusable or disposable compartment that separates the digital circuit from the chemical agents. The reusable compartment is sufficiently ruggedized to withstand the ignition of the primer and the detonation of the chemical agents to be reused with one or more additional disposable cartridges. In one implementation, the delivery receptacle uses a commercial airbag initiator as the primer, which is arranged in relation to the one or more chemical agents so that when the initiator is activated, it generates a pressure wave that expels the one or more chemical agents from the grenade.

A reusable simulated weapon device includes a holding chamber and an expansion chamber for receiving expanding gas. A shuttle is slidable between a closed position that blocks communication between the holding chamber and the expansion chamber and an open position that allows communication. A pilot valve allows pressurized gas in the holding chamber to drive the shuttle into the open position. A firing pin opens the pilot valve. The firing pin has an armed position, in which a protrusion engages with a recess to hold the firing pin against a spring. The firing pin can be released from the armed position in response to an impact to the device. When the firing pin is released, the spring drives the firing pin to actuate the pilot valve, causing the shuttle to slide from the closed position to the open position to allow gas to move into the expansion chamber.
