I believe that has stopped here, after an accidental death..... that may have been a reason why the blooding episode may have acted as replacement training.
I'm aware the SAS take their training seriously as BHP and Union members - with approval of both parties - found out on a Bass Strait Oil Rig exercise.
Some workers on the Oil Rig were injured! Even the reservist SAS members have been known to damage motel property on these exercises.
