The OSS Norwegian Special Operations Group in World War II

The Operational Groups (OGs) are the unsung heroes of the OSS, and this story is about the Norwegian OGs, who operated deep behind enemy lines in France in 1944, and in Norway, China, and Indochina in 1945. OGs were the Infantry of the OSS. They were uniformed military personnel designed as hard-hitting units trained to operate deep behind enemy lines to conduct sabotage upon Axis forces. The OGs were trained in parachuting, demolitions, weaponry, commando tactics, communications, amphibious warfare, and skiing.
