The US Army's Delta Force is the only official US counter-terrorism unit focused on hostage rescues, counter-insurgency and counter-terrorism.
To be selected for this specialty force team, an individual must undergo a rigid physical test that begins with sit ups and push-ups and a 3 mile run – all to be completed within an undisclosed time frame.
Once the above requirements are successfully completed, the recruit is then permitted to enter into the actual 6 month training program for the Delta Force.
