A small group of ordinary Australians are about to take part in one of the toughest military Selection courses in the world. A physically, and psychologically grueling 6 weeks, designed to identify potential candidates for the 1st and 2nd Commando Regiments - extremely specialised, combat capable Australian Special Forces Units. More than half of the applicants attempting the course will not succeed. The high standard of performance demanded of selection will push, and challenge all of those that start. For many applicants, it will overwhelm them. But for a select few, it will grant them access to one of the most sophisticated and extensive military training continuums in the country.
