I'll tell you this about the selection....
Little effort was made even to concurrently hike the advanced special forces skills training capacity of the special Forces Training school.
In one instance, a batch of 130 volunteers was sent to SFTs for probation (though SFTs had no such charter) and standards were diluted to pass at least 50 percent of them.
Concurrently, a larger batch was made to do a three-month probation at the Parachute Regiment Training Centre itself, including one month of the Para Basic Course. Thereafter, they were simply ‘posted’ to special forces units. This was in complete disregard of the requirement of six-month probation to be done in the respective special forces unit under the supervision of the concerned commanding officer.
Many of such intakes were sub-standard, even poor in battle physical efficiency tests (BPET), and the older junior commissioned officers (JCOs) and noncommissioned officers (NCOs) were heard commenting, “Sahib total pura ho raha hai.”
Since these individuals were ‘posted’ to units, to revert even one individual, the commanding officer was required to declare him ‘unsuitable’ and obtain sanction of army Headquarters prior to such reversion. This meant delay in months with ample chance of non-acceptance by the Para officer dealing with the issue in the Infantry Directorate.
