The purpose of this United States Marine Corps USMC manual, Marine Corps Doctrine Publication 7 Learning February 2020, is to describe the Marine Corps' learning philosophy and explain why learning is critically important to the profession of arms. While many of the concepts in this publication have been passed on by Marine leaders throughout our history, this publication seeks to formalize them and provide aspirational goals. Learning is an institutional priority and a professional expectation for all Marines. This mentality is key to the Marine Corps becoming a more effective learning organization. The most important factor in this philosophy is the importance of continuous learning throughout our careers for warfighting. Continuous learning is essential to maneuver warfare because it enables Marines to quickly recognize changing conditions in the battlespace, adapt, and make timely decisions against a thinking enemy. These skills required in war must be learned, developed, and honed over time-if neglected, they quickly atrophy. Marines leverage the art and science of learning, technologies, and learning environments that reflect the changing operational environment to tailor learning and provide each other with constructive feedback. Leaders hold Marines to high professional standards of performance, conduct, and discipline-to include learning. As Marines rise in rank and position, continuous learning and developing our professional skills are a professional expectation. We must make the most of every learning opportunity, fostering our subordinates' learning while continuing our own.
