Final answer:
The 'Strengthen' function of COSC is focused on building psychological resilience, not physical fitness, operational planning, or technological advancements. It involves equipping service members with skills and resources for effective coping, maintaining mental health, and preventing stress disorders.
Step-by-step explanation:
The Combat Operational Stress Control (COSC) leadership function 'Strengthen' is aimed at building psychological resilience among service members. This function recognizes that stressors are an inherent part of combat and military operations, and it seeks to equip individuals with the skills and resources needed to cope effectively with these stressors, enhance their mental health and functioning, and prevent the development of stress-related disorders. While physical fitness is important, the 'Strengthen' function is primarily concerned with fostering cognitive and emotional skills that contribute to resilience, such as problem-focused and emotion-focused coping strategies, a sense of perceived control, and the cultivation and maintenance of a strong system of social support - all of which are vital in health and longevity.
