Chapter 2
2-37. The running estimate parallels the MDMP. The mission analysis, facts and assumptions, and analysis
of the mission variables furnish the structure for running estimates. In the running estimate, the engineer
staff continuously considers the effects of new information and updates the following:
� Facts.
� Assumptions.
� Friendly force status (assessment of M/CM/S capabilities to ongoing and planned operations).
� Enemy activities and capabilities (that can affect current operations and future plans).
� Civil considerations (effects on current engineer operations and future plans).
� Conclusions and recommendations.
2-38. During preparation, estimates continue to track resource status. The priority for assessment is on
answering PIRs and FFIRs that fall within the engineer area of expertise. Assessing during preparation also
includes confirming or disproving any assumptions that were made during planning.
2-39. During execution, estimates focus on identifying any variances, assessing their effect on achieving
the end state, and recommending corrective actions to keep the operation within the commander’s intent.
Assessments also address the supportability of possible sequels and future operations. During operations,
running estimates are usually presented orally, especially during preparation and execution. Written
estimates may be prepared to support contingency planning during peacetime. Even then, they are normally
prepared only at higher-level headquarters.
2-40. The running estimate provides the basis for action. When an estimate reveals a variance that requires
correction, staff representatives act within their authority to correct it. When the decision required is
outside their authority, they present the situation to the staff officer who has the authority to act or to the
commander. When the estimate reveals information that answers an information requirement, especially a
CCIR, engineer staff representatives send that information to the element requiring it. Engineer staff
representatives do more than collect and store information; they process it into knowledge and apply
judgment to get that knowledge to those requiring it.
ASSURED MOBILITY
2-41. Assured mobility is a framework of processes, actions, and capabilities that assure the ability of the
joint force to deploy and maneuver where and when desired, without interruption or delay, to achieve the
mission. (FM 3-34) Assured mobility is an integrating process for the warfighting functions similar to that
of ISR synchronization, targeting, composite risk management (CRM), and IPB. As an integrating process,
assured mobility provides linkage between the tasks associated with M/CM/S and their roles across the six
warfighting functions. It strives to ensure freedom of maneuver and preserve combat power throughout the
AO as it seeks to exploit superior SU. This construct is one means of enabling a unit to achieve the
commander’s intent. Assured mobility emphasizes proactive mobility and countermobility (and supporting
survivability) actions and integrates all engineer functions in accomplishing this. Assured mobility is
broader than the term “mobility” and should not be confused with the limited application of the mobility
operations as described in FM 3-34.2.
2-42. While the ENCOORD plays a primary role in assured mobility, other staff members support its
integration and also have critical roles. The ENCOORD or the assured mobility section leader (if
designated) plays an integrating role in assured mobility that is similar to the role played by the S-2 in the
IPB integrating process. Other staff members also integrate M/CM/S tasks as a part of assured mobility.
Examples would include providing traffic regulation in the maneuver space or handling displaced persons.
2-43. The framework of assured mobility follows a continuous cycle of planning, preparing, and executing
decisive and shaping operations. Achieving assured mobility rests on applying six fundamentals that
sustain friendly maneuver, preclude enemy ability to maneuver, and assist in the protection warfighting
function. The fundamentals of assured mobility are—
� Predict. Engineers and other planners must accurately predict potential enemy impediments to
joint force mobility by analyzing enemy TTP, capability, and evolution. Prediction requires a
constantly updated understanding of the OE.
