How to deal with incidents involving armoured vehicles There has been an accident involving a British Army Jackal and pedestrians, leaving the crew injured. The medics and rescuers who arrive first have to begin appropriate treatment and remove any casualties after the incident. Thankfully, this is all just an exercise. "So, with the scenario that we have today, one of the Jackals has come off the road," Sergeant Ilaitia Ratuqalovi, an instructor, said.
