What is the desired effect of OPSEC?

The desired effect of Operational Security (OPSEC) is to influence the adversary's behavior and actions. OPSEC is a comprehensive process of identifying critical information and subsequently analyzing actions that could allow adversaries to gain access to that information. By implementing effective OPSEC measures, military forces can protect sensitive information that, if revealed, could provide adversaries with an insight into strategic plans or operational capabilities. This protective strategy not only safeguards essential operations but also ensures that adversaries are left guessing and uncertain, which can alter their decision-making and actions in a way that favors the military forces employing these tactics.

Other options do not reflect the core aim of OPSEC. Hiding information from allies could undermine trust and collaboration, while enhancing internal security measures is a broader concept that can encompass more than just OPSEC. Additionally, the notion of reducing military resources does not align with the primary focus of OPSEC, which is more about controlling information rather than directly affecting resource management.
