This is how the Marines groom their top operators

An average of 11 months of grueling training and the mastery of seven weapons are just some of the hurdles to join the elite tier of the Corps'.

After serving three years as a Marine, MARSOC candidates arrive at Camp Lejeune, North Carolina, in the best shape of their lives.

Some of the physical assessments include a 300 yard swim in cammies and a brutal 12-mile timed rucksack run carrying 45 pounds of gear.

Come along to MARSOC and see what the training is like.

MARSOC training begins with Phase One, a 10 week long course that focuses on basic skills that all operators will need to master.

These skills include general fitness ...

All Marines must also master survival skills such as Survival, Evasion, Resistance, and Escape (SERE) training and Tactical Combat Casualty Care (TCCC).

This second phase involves small boat operations and information collection.

After completion of Phase Two, successful Marines enter into 5 weeks of Close Quarters Battles training.

This includes rifle and pistol marksmanship lessons ...

... As well as learning the tactics and techniques required for successfully conducting raids on urban, rural, and maritime objects.

Phase Four is the final section of the course and lasts seven weeks.

This phase, dubbed Irregular Warfare, requires that Marines demonstrate a complete mastery of all preceding skills.

In the fourth phase, operators will pair with soldiers from a participating partner nation.

MARSOC operators are required to then train, advise, and successfully operate with the partner nation forces. MARSOC has operated in more than 40 countries.
