Battle cries like "Rangers Lead The Way," "Night Stalkers Don't Quit," "Who Dares Wins," and "Oppressor Libre" represent the special operations units that have become an increasingly critical part of the U.S. armed forces. Special operations forces (SOF), though small in numbers, provide the National Command Authority a critical capability anywhere on the globe. Comprised of select servicemen from all services, they capitalize on the human dimension of warfare enhanced by technology. In SOF units, people are more important than hardware. They operate best in the asymmetrical environment, which is full of uncertainty, ambiguous requirements, fleeting enemies, and austere environmental conditions. These characteristics make them ideally suited for the war on terrorism.
