What does the third general order instruct a soldier to do?

The third general order instructs a soldier to report violations of special orders and emergencies, which retains a focus on vigilance and accountability. This order emphasizes the importance of communication and situational awareness within a military context. By reporting any discrepancies or emergencies, soldiers help maintain the integrity of operations and ensure safety for themselves and their comrades. This obligation forms a critical part of a soldier's duties, reinforcing the chain of command and operational effectiveness.

The incorrect options involve other duties that are vital but pertain to different specific orders or responsibilities. While guarding a post, maintaining weapon readiness, and following commands from superiors are all critical aspects of military conduct, they correspond to different general orders that focus on physical presence, equipment readiness, and obedience to authority, respectively. Thus, understanding the specific focus of the third general order on reporting helps clarify its significance within the broader framework of military duty.
