What action is taken when a patrol detects the enemy but is not detected itself?

When a patrol detects the enemy but remains undetected itself, the tactical approach is to halt in place quietly until further instructions. This decision allows the patrol to gather more intelligence on the enemy's movements and intentions without alerting them to their presence. By maintaining silence and stillness, the patrol can assess the situation, consider potential actions, and wait for further guidance, thereby increasing their chances of executing a successful maneuver while minimizing risk.

The emphasis on remaining undetected highlights the importance of stealth in military operations. Observing the enemy's behavior in this scenario provides critical information that could influence the patrol’s next steps, be it preparing for an attack, planning an ambush, or deciding to withdraw safely.

In contrast, continuing to move toward the objective without pause could lead to detection and engagement, compromising the patrol’s position. Initiating loud verbal commands would undoubtedly reveal their presence to the enemy, making the situation more perilous. Similarly, retreating immediately might unnecessarily alert the enemy and miss the opportunity to capitalize on the element of surprise or to gather vital information. Thus, halting quietly is the most prudent action in this context, allowing for tactical evaluation while safely remaining hidden.
