Open Fire

Soldiers like Sergeant Jennings never forget the feeling of firing weapons like the Carl Gustaf recoilless rifle, known as the 84.

To demonstrate the safety protocols in place to protect soldiers, the Australian Army gave 7.30 footage of infantry soldiers training with the weapon behind three-walled concrete firing bays designed to protect soldiers if a rocket detonated short of its target.

A 2021 US Marine Corps technical operator manual seen by 7.30 instructs marines firing the same weapon to do so from an open firing point to reduce the risk of the concrete barriers amplifying the blast overpressure back onto soldiers.

Uniformed Services University researcher Joshua Whitty, from the US-based CONQUER blast monitoring project, said the Australian Army had "inadvertently created a very real hazard that affects everyone in those firing points" by using the concrete barriers.
