Selection is demanding and has a drop out rate of about 70–80 per cent. Three of their 14 months of training in Manesar, Haryana, are devoted to the basics. Physical fitness training has 26 elements, ranging from a cross-country obstacle course to jumping from heights and across divides and scaling different kinds of terrain. One endurance test involves martial arts, target shooting at the end of an obstacle-ridden cross-country run. This is meant to gauge the candidate's performance under conditions of stress and exhaustion. Those who successfully complete the tests are sent for nine months of advanced training.
