Which security program involves identifying critical information and analyzing friendly actions during military operations?

The correct answer reflects the definition of Operations Security (OPSEC), which is a crucial aspect of military security programs. OPSEC focuses on identifying and protecting critical information from being discovered by adversaries during military operations. This involves analyzing both the friendly actions undertaken during these operations and the potential vulnerabilities that could be exploited. The process helps ensure that the actions taken by military forces do not inadvertently reveal important information that could aid the enemy.

As OPSEC identifies and assesses information that could be detrimental to operations if disclosed, it plays a vital role in maintaining operational effectiveness and protecting national security. This proactive approach to protecting sensitive information ensures a tactical advantage in military operations by concealing intentions and capabilities from adversaries.
