This manual, Marine Corps Warfighting Publication MCWP 12-10 Every Clime and Place February 2019, provides a foundational discussion of the environments where Marines are expected to fight. It discusses the application of climate, weather, and geographical analysis to military planning by introducing each environment and providing considerations for each. The purpose of this publication is to outline the impact of environment, inclusive of terrain and weather, on Marine Corps operations.
This publication is designed for all Marines. Since the Marine Corps supports geographic combatant commanders across the globe, Marines must be ready to adapt to diverse environments. Operational flexibility is a major hallmark of the Marine Corps legacy. As we continue to uphold this legacy, Marines must always be ready to fight in every clime and place.
