10. Special Services Group
While the name itself is straight to the point and simple as compared to other special forces, the Special Services Group of the Pakistan army is not one to fail even the toughest of missions. This group is one of the largest special forces in the world. Headed by a major-general, the Special Services Group is made up of 8 battalions, each comprising of 700 personnel.
To get into this elite group, a candidate must have at least 2 years of experience in the military. After that, candidates will have to undergo a rigorous 9-month training course made for the Special Services Group. One of the many exercises during the 9-month training course is a 36-mile march in full gear with a time limit of 12 hours. During this march, the candidates will run for about 5 miles in 50 minutes. The training course is so tough, only 5% of the candidates make it through to become a member of the group.
