ANNEX F (ENGINEER) TO OPERATION ORDER NO____________________.
1. SITUATION.
a. Enemy forces. Include a detailed description of enemy engineer units and assets and known
obstacles. Refer to Annex B (Intelligence) as required.
b. Friendly forces. State the higher-headquarters concept of engineer support and provide the
adjacent unit concept of engineer support.
c. Environment.
(1) Terrain. Describe how the terrain affects engineer operations.
(2) Weather. Describe how the weather affects engineer operations.
(3) Civil considerations. Describe the impacts of civil considerations on engineer operations.
d. Attachments and detachments. List all attached and detached M/CM/S assets to clarify task
organization. Highlight changes in engineer task organization occurring during operations and the
effective times or events.
2. MISSION. State the engineering mission in support of the operation.
3. EXECUTION.
a. Scheme of engineer operations. Same scheme as in the base order.
� Provide a narrative of M/CM/S, general engineering, and geospatial engineering tasks required
to enable success of the supported scheme of maneuver.
� List the essential tasks for M/CM/S (include task and purpose for each) and explain how each
supports the scheme of maneuver.
� Ensure that the scheme of engineer operations corresponds to the maneuver unit concept of
operations, which provides the foundation and structure for engineer operations. If the
operation is phased, the scheme of engineer operations is also phased using the same
phases. If the operation is not phased, use the same format as the supported unit concept of
operation.
� Address required areas under each phase in order of priority by phase. If there is no support
provided in an area during a phase, do not mention that area. The engineer effort addressed
under each phase applies to the supported unit during that phase, regardless of when the effort
is completed. For example, engineers emplace obstacles during the preparation phase of the
defense, though the obstacle intent is mentioned during the execution phase.
� General comments. Provide a brief, one sentence comment that broadly describes
engineer support for the phase.
� Mobility. Explain each mobility task (breaching, reducing obstacles, marking lanes,
providing guides, maintaining a route), relative location (route, objective), priority of
reduction asset used (use plows first, then MICLICs), and that maneuver unit being
supported.
� Countermobility. Identify each obstacle belt, group, or individual in order of priority, intent
(target, relative location, and effect), maneuver unit responsible, and indirect fires
allocated. Provide execution criteria for reserve targets and situational obstacles.
� Survivability. Identify each survivability task, its relative location (BP, EA), and the unit it
supports. This includes smoke operations when used for survivability purposes; for
example, obscuration during breaching.
