The Operation Order, or OPORD, is a structured, formatted expression of a commander's mission intent and concept for conducting operations to accomplish mission objectives. The OPORD, in its most basic form, provides subordinate commanders, staff, and personnel with instructions on how to execute the various steps of a mission safely and effectively.
The standard OPORD is constructed in five paragraphs:
The Situation paragraph provides details about what is going on that warrants the mission to be conducted. The Situation paragraph consists of four sub-sections:
a. Terrain: What the physical Area of Operations (AO) consists of and how it can positively or negative impact the mission
b. Weather: How the forecasted visibility, day/night conditions, precipitation, and other factors influence the operation
The Mission paragraph provides a clear and concise statement as to the unit's task. This is the who, what, where, when, and why of the mission.
The Execution paragraph—usually the largest portion of the OPORD—provides a detailed outline of how the mission will be carried out by the unit. The Execution paragraph includes the:
The Execution concept is often expressed as five phases of the mission sequence:
The Service Support paragraph—also utilized as the Administration & Logistics or Sustainment paragraph (becoming the more modern approach for military OPORDs)—explains how the operation will be supported logistically (i.e., materials and transportation) and includes special personnel services, such as medical support, chaplain support, and/or financial services, all as appropriate for the mission.
It is common that a separate Service Support Plan is developed due to the complexities of support operations and since the support elements are often not under the command governing this OPORD.
The Command and Signal paragraph consists of two sub-sections which detail the operation's concepts for:
OPORDs are primarily constructed by the S3 Operations office to provide:
In addition to writing the OPORD, the S3 may be tasked with conducting the briefing the of OPORD to the echelon staff and subordinate commanders.
The S3 is also often responsible for facilitating After-Action Reviews (AAR) so that they can restate the purpose and intent of the mission—based on what the OPORD contained—and review the actual execution of the mission to see what parts of the OPORD were irrelevant or ineffective for the personnel executing it.
An OPORD is never considered authorized for execution unless the commander has approved it by signing it.
In many instances, the next-higher echelon commander may wish to endorse subordinate echelon OPORDs to ensure that they align with the more strategic mission plan. Commanders should always try to review their OPORD with their superior commander prior to issuing it to their troops.
Commanders must remember that the OPORD is the final step in the "First Third" portion of the One-Thirds, Two-Thirds planning timeline—the seventh step in the Troop Leading Procedure.
The OPORD must be developed with enough detail and quality so that personnel can appropriately prepare themselves to conduct the mission in a timely manner.
