They told about how the recruits are divided into one team which is left in a jungle who are ambushed on the 7th day after bein left hungry for days.
The guys doing the ambush are the blue team or SF operators who capture them and then beat the hell out of them in interrogation.
Those who reveal the secrets are treated well but failed...those who dont are treated more badly.
Those who dont give up for a week of interrogation and hunger are inducted and trained for 1 yr or more before being called a operator.
This happens in a himalayan town i wont name.
