Which of the following is NOT considered a duty of a soldier?

Refusing orders from superiors is not considered a duty of a soldier. The military operates on a strict hierarchy, and following orders from superiors is a fundamental expectation of service members. This chain of command is essential for maintaining discipline, operational effectiveness, and unity within the ranks. Soldiers are trained to execute lawful orders as part of their duties, and refusing orders can lead to consequences, including disciplinary action, because it undermines the authority and structure that is crucial for military operations.

On the other hand, completing mandatory training, maintaining physical fitness, and following established protocols are all essential duties of a soldier. These responsibilities ensure that personnel are properly equipped, physically capable, and knowledgeable about procedures necessary to perform their roles effectively in various situations.
