'Dean Gallagher, 34, and Chase, 26, are brothers. Competitive alpha males, they argue over everything, agree on nothing, but defend each other from outsiders no matter what. They’re members of Rescue Special Ops. Experienced paramedics in peak physical condition, they're skilled in abseiling, rock climbing, surf and sea rescue, 4WD driving and fire brigade procedures. They're the first to be called in for any natural or man-made disaster, salvage or rescue operation.'
