There exists among the world's armies a proliferation of special forces groups. Today's smaller armies, especially those of developing nations, demand maximum efficiency in force structure and employment. Mountain, jungle, arctic and desert areas require special purpose units trained, conditioned, and equipped to master these environments. This volume by ex-weapons specialist in the US 7th Special Forces Group, Gordon L. Rottman, details the insignia of a myriad of special forces groups from all parts of the globe, from Portugal's Commando Regiment to the North Yemen 'Al Mithalaat' Brigade, with a wealth of illustrations and photographs, including 12 full page colour plates by Simon McCouaig.

Gordon L. Rottman entered the US Army in 1967, volunteered for Special Forces and completed training as a weapons specialist.

He was a Special Operations Forces scenario writer at the Joint Readiness Training Center for 12 years and is now a freelance writer, living in Texas.
