They are considered to be high-level experts in mountaineering, and are hired to instruct or lead individuals or small groups who require this advanced expertise.
Typically lasting between 3 and 7 years, mountain guide certification requires a high level of commitment, dedication and technical skill to achieve.
In addition to assuring safety, professional mountain guides frequently offer other desirable services to their clients.
These services can significantly improve the alpine experience, especially when the client climber has limited time or equipment, lacks a qualified partner or is visiting an unfamiliar area.
Among the alpine instructors on the individual front sections were mountaineers such as Julius Kugy in the Julian Alps and Leo Handl in the Marmolada.
Georg Bilgeri's notes show that by January 22, 1918, 146 officers and 2,302 men were trained as military mountain guides.
