Analyze Friendly Mission and Capabilities
Engineer Running Estimate
F-18. The ENCOORD must understand the friendly mission, commander’s intent, and concept of the
operation and understand how engineer capabilities contribute to the mission. To estimate the friendly
mission and M/CM/S capabilities, the ENCOORD must—
� Consider the friendly mission.
� Evaluate friendly engineer capabilities and their impact on accomplishing the mission.
� Estimate the available engineer assets based on the task organization of—
� Maneuver forces.
� Engineer forces.
� Higher engineer headquarters.
� Adjacent engineer units.
� HN or contractor capabilities.
� Consider the availability of critical resources.
� Estimate the total engineer capability based on engineer planning.
F-19. The ENCOORD considers all assets that can provide engineer capability, including task-organized
engineer units, nonengineer unit assets have (mine plows), assets under the control of higher engineer
headquarters (HN and contracted civilian support), and adjacent units. This understanding facilitates
requests for additional resources based on shortfalls identified during mission analysis and COA
development.
F-20. Having determined the assets available, the ENCOORD works with the S-3 to determine the
estimated time available. The ENCOORD can apply standard planning factors or known unit work rates to
determine the total engineer capability. For example, in the offense, the ENCOORD focuses on the total
amount of breaching equipment (MICLICs, AVLBs, engineer platoons, and any engineer augmentation)
and translates that into the number of breach lanes. In the defense, the ENCOOD determines the number of
minefields (or linear effort in kilometers), hull or turret defilade positions, and tank ditches that engineers
could construct with available resources. In stability operations, the focus may be on the number of
clearing teams that can be created. The ENCOORD uses these capability estimates during COA
development.
F-21. The ENCOORD combines the analysis of terrain and weather, and the analysis of the enemy and
friendly mission, and M/CM/S capabilities to form facts and assumptions about the—
� Likely enemy engineer effort.
� Most probable enemy COA.
� Potential enemy vulnerabilities.
� Critical friendly requirements.
� Impact of the preceding factors on the mission.
Determine Constraints
F-22. Constraints are restrictions placed on a unit by higher headquarters. They dictate an action or
inaction, thus restricting the freedom of action a subordinate commander has for planning. Constraints can
take the form of a requirement to do something. For engineers, this could include designated reserve
targets, obstacle belts (with intents), and lane requirements. Constraints can also prohibit action, such as
stated approval authority for use of SCATMINEs. Obstacle zones and belts are also examples of
constraints because they limit the area in which tactical obstacles can be placed.
Determine Risk
F-23. Risk (tactical and accidental) consideration begins during planning, as commanders designate and
weigh the decisive operation. To do this, they accept risk elsewhere to mass the combat power needed to
accomplish the mission. A commander may specify an acceptable risk to accomplish the mission. For
