Beginning in 1995, there became an increasing necessity within the Department of Defense (DoD) to provide a means of advanced life-support measures for specific special operations medical personnel. Providing primary-care medicine in tactical environments wherein definitive care would be indefinitely delayed or denied by the host-nation facilitated the need for specialized training to meet these requirements. Concurrent with the development of this medical program was the additional need for special operations personnel to master certain diverse operational techniques.  The areas of particular interest were the following:

Fundamental Mountaineering Skills

Advanced Mountaineering Skills and Team Movement

Advanced High-Angle Rescue Operations

High-Angle Rescue and Urban Vertical Assault (Atlas Devices)

Lead climbing

Multi-pitch Lead Climbing
(SPI certification)

 Extreme Cold-Weather Operations
