What choices may be signaled by changes in behavior and discernible only to the individual soldier or comrades?

Changes in behavior, such as increased alertness, hypervigilance, or withdrawal, may indicate possible underlying emotions like fear, stress, or mental health concerns that are discernible only to the individual soldier or comrades who are closely observing them. It could also signify personal struggles or challenges that the individual may be facing in their personal life or on the battlefield. These changes may warrant further attention and support from leaders or mental health professionals.
