The US military's special operators are the most elite in the world.
Depending on the unit, special operators are charged with a variety of missions: counterterrorism, direct action (small raids and ambushes), unconventional warfare (supporting resistence against a government), hostage rescue and recovery, special reconnaissance (reconnaissance that avoids contact behind enemy lines), and more.
