Shit happens.... About 10 years ago, during a demonstration of an hostage rescue operation performed by the GCP of 3e RPIMa, one of the team members had live rounds in his magazine, mixed with blank ones. The demo was done in front of the public, during a PR operation called in French "Opération Portes Ouvertes" (a day when military units open their doors to the public, a bit like the kermesse organised by the Legion for Camerone). The operator shot a burst of three and a live round was fired, gravely wounding a young boy who was attending the ‘show’ with his parents. Fortunately, the GCP operator had fixed his blank-firing adapter and the victim was ‘only’ hurt by fragments of it that hit him when it was shattered by the live round. Otherwise he would surely have been killed.
The incident raised a hell of questions on the compliance with the procedures normally in place to control the use of live ammo and the reason why the operator had managed to keep live rounds after a shooting session done in the days before, instead of returning those unused to the armory...
