What is the fourth paragraph of the OPORD format?

The fourth paragraph of an Operational Order (OPORD) format is focused on Sustainment. This section outlines the logistics, administrative, and medical support necessary to execute the mission effectively. It details how resources will be managed and provided, ensuring that the unit has what it needs to complete its tasks. This includes information on supplies, transportation, maintenance, and personnel support.

In the Sustainment paragraph, commanders articulate the plan for sustaining operations over time and highlight key aspects like the distribution of supplies, the location of vital support units, and any logistical challenges anticipated. This information is critical for ensuring that the unit can maintain operational readiness and effectiveness throughout the mission's duration.

While the other sections of OPORD serve their purposes—such as providing situational awareness in the Situation paragraph, detailing the plan of action in the Execution section, and establishing command relationships in Command and Signal—they do not cover the logistical aspects that Sustainment addresses. Thus, pinpointing the fourth paragraph as Sustainment reinforces the importance of logistical planning in successful mission execution.
