Ski warfare is first recorded by the Danish historian Saxo Grammaticus in the 13th century. During the Battle of Oslo in 1161, Norwegian troops used skis for reconnoitering. They were also used in 1452 in Sweden, and in the 15th to 17th centuries by various other Scandinavian countries. In 1767, military ski competitions began. They evolved into the biathlon.
World War IEdit
During World War I the Italian Army raised 88 Alpini Battalions. Their purpose was to fight summer and winter in the highest regions of the Alpine Arch. Most of the battalions were dissolved after World War I. Only nine Alpini regiments remain in service today, and only four still train every soldier in ski warfare: the 4th Alpini Parachutist Regiment, 5th Alpini Regiment, 6th Alpini Regiment and 7th Alpini Regiment.
World War IIEdit
Ski troops played a key role in the successes of the Finnish war effort against the Soviet Union during the Winter War in 1939. Forested, rural terrain with no roads was used by Finnish ski troops with great success against the advancing mechanized Soviet troops. In the Battle of Suomussalmi, two Soviet mechanized divisions (45,000 men) were annihilated by three Finnish regiments (11,000 men).
The most common transportation for Norwegian soldiers during the Norwegian Campaign in 1940 was skis and sleds, and in Operation Gunnerside, paradropped Norwegian commandos covered a large distance using skis in order to reach and sabotage the heavy water plant Vemork at Rjukan in Telemark, Norway, which was being used by the Germans as part of their nuclear research programme.
Ski warfare even extended to the Middle East where the Australian Ski Corps were deployed against Vichy French forces in the mountains of Lebanon.
Swedish, Finnish and Norwegian defense forces use skis in cross country skiing but also by pulling squads of soldiers with tracked transport vehicles or snow mobiles. One or two ropes hang from the end of a tracked vehicle such as the famous Swedish Hägglunds Bandvagn 206 or the Finnish Sisu Nasu and troops hang onto the ropes with their hands and ski-poles.
