Final answer:
The most effective non punitive measure a commander can employ is implementing informal positive sanctions, using rewards and humaneness combined with strict discipline to maintain control while building loyal and cooperative troop relationships.
Step-by-step explanation:
One of the most effective nonpunitive measures available to a commander is the implementation of informal positive sanctions. These are methods that involve the use of rewards and incentives to encourage desired behaviors among troops, rather than punishing them for misdeeds. Applying humanity and compassionate leadership can build a strong bond between soldiers and their commander, fostering an environment where discipline and control are maintained through mutual respect and loyalty, rather than fear of punishment.
As suggested in the reference provided, maintaining iron discipline is critical, but it must be balanced with humane treatment of soldiers. This balance ensures that soldiers feel a sense of attachment and commitment to their unit and leader, which can be more effective than the direct application of formal punishments. Thus, nurturing such personal relationships and monitoring for infractions positively could help avoid collective action problems without the need for established formal mechanisms.
