Final answer:
Commanders may use deception to maintain secrecy during a relief in place, as historical strategies by Sun Tzu in 'The Art of War' indicate the importance of keeping strategies secret for success in warfare.
Step-by-step explanation:
Commanders may use deception measures when conducting a relief in place to maintain secrecy. This military tactic involves misleading the enemy about the intentions, capabilities, or locations of armed forces. Historical strategist Sun Tzu, in his work The Art of War, emphasizes the importance of deception in military strategy. For example, deceiving the enemy by hiding the true numbers or movement of troops can be crucial for achieving a surprise advantage and success in warfare, accommodating to the enemy's purpose while remaining unpredictable. The passages quoted from Sun Tzu reflect on the significance of misleading the enemy and the benefit of keeping one's own strategies secret, hence the use of deception.
