Several soldiers tasked with preparing parachutes for military exercises are facing possible removal from the army after testing positive for prohibited substances. The ABC has reported that six positive drug tests were discovered just days before a training jump that resulted in the death of Special Forces member, Lance Corporal Jack Fitzgibbon. However, the Defence Department maintains that those who prepared Lance Corporal Fitzgibbon's equipment tested negative for any substances. Defence correspondent Andrew Greene has more on this developing story.
