  5-8. The S-4’s analysis also includes estimated attrition based on likely outcomes of subordinate missions.
  Analysis of estimated attrition primarily focuses on critical systems. The S-1, in coordination with the
  surgeon, assists by projecting potential personnel losses (through development of the casualty estimate). To
  perform this analysis, current unit personnel and equipment densities, standard planning factors, operations
  logistics software, and historical data are used in conjunction with the operations logistics plan. When
  analyzing COAs, this projection helps the commander understand the potential losses and associated risks of
  each COA.
  5-9. To understand the MEB capabilities and determine support requirements, logistics planners apply a
  METT-TC analysis to the operation. Table 5-1 gives an example of general sustainment considerations for
  tactical operations.

  5-10. The S-4, in coordination with the surgeon, S-1, and all elements of the MEB staff, must balance support
  requirements and priorities with available sustainment capabilities. They consider existing stockage,
  anticipated receipts, capacities, and capabilities. They must assess the status of all sustainment functions
  (logistics, personnel services, financial management, and HSS) required to support the MEB and compare them
  to available capabilities. They identify potential shortfalls then take or recommend actions to eliminate or
  reduce their effect on the operation.
