Which activity is NOT a major mission command activity performed during operations?

In mission command, the primary activities revolve around planning, executing, and continuously assessing operations to adapt to changing conditions on the battlefield. Each of these activities serves a vital role in ensuring that leaders can make effective decisions and maintain the overall flow of operations.

Deploying, while an essential part of military operations, does not fall under the direct umbrella of mission command activities. Instead, deploying refers to the process of moving forces into position for action, which is typically a logistical and operational activity rather than a direct function of command and control decision-making. The focus of mission command activities is more on how leaders issue commands, manage resources, and ensure effective execution, rather than the act of deploying forces themselves.

This distinction is important in understanding the framework of mission command and how various operations are carried out within a military context. Looking at the other options, they are all integral to the continuous cycle of assessing the situation, developing plans, and executing operations, aligning directly with mission command principles.
