What is the term for the military training phase that focuses on physical endurance?

The term that refers specifically to the military training phase emphasizing physical endurance is known as Physical Conditioning. This phase is designed to enhance the physical capabilities of service members, equipping them with the stamina and endurance necessary to perform effectively in demanding situations. Physical Conditioning typically involves a variety of aerobic and endurance-building activities to improve cardiovascular fitness, muscular endurance, and overall physical health.

In contrast, Mental Fortification generally pertains to strengthening mental resilience and preparedness rather than physical endurance. Combat Readiness addresses a broader range of skills and preparedness for deployment scenarios, which includes physical fitness but also encompasses tactical training and operational readiness. Strength Training focuses specifically on building muscle strength rather than endurance, thus highlighting weightlifting and resistance exercises rather than the holistic cardiovascular focus found in Physical Conditioning. Therefore, Physical Conditioning is the most fitting term for a training phase dedicated to enhancing physical endurance.
