NSG recruits learn the art of one shot one kill as part of their rigorous 12-week basic training course. The regimen begins at 5 a.m. The morning PT is only a warm-up for the 5 km run, with their 18.5 kg load of weapons, rucksack and water bottle. The 770-metre obstacle course specially designed for the NSG. There are 26 obstacles, including climbing 16-foot ropes and jumping across flaming walls. It's the toughest obstacle race anywhere in the military world, more punishing than even the ones used in Israel and Germany to train para-commandos.
