Marine Corps Reference Publication MCRP 12-10A.3 (Formerly MCRP 3-35.1C) Mountain Leader's Guide to Mountain Warfare Operations 2 May 2016 Marine Corps Reference Publication 3-35.1C, Mountain Leader's Guide to Mountain Warfare Operations, is a reference for trained summer mountain leaders to use during operations in complex, compartmentalized, mountainous, high altitude, alpine, and glaciated terrain. This manual is not exhaustive and must be used together with the mountain warfare operations doctrinal series, as duplication of material is being avoided and target audiences vary. This publication covers terrain; weather; rope skills; rope systems; climbing; fixed ropes; rappelling; casualty evacuation; planning considerations across all six warfighting functions; chemical, biological, radiological, and nuclear considerations; glacier operations; and processes used to guide units through mountainous/alpine terrain. It focuses on a standard method of instruction and stresses only the skills necessary for Marines to go into combat. Because of rapid turnover in personnel, the many units that train annually, the multitude of training commitments, and the short season, the Marine Corps Mountain Warfare Training Center cannot train all personnel or units. In combat, Marines may receive instruction from their unit's qualified summer mountain leaders. This publication specifically supports the mountain leader's ability to provide that instruction.
