Optimum Logistical Footprint: Defining the logistic structure required and sizing the logistics footprint to deploying forces are essential to effectiveness. The goal is to avoid burdening strategic lift, infrastructure, and the commander with more support than is necessary, yet deploy minimum assets necessary to optimize throughput of units and materiel. Supporting assets must be deployed in a properly timed sequence to leverage their capabilities. Sizes of logistical footprints may be increased to reduce vulnerability of the overall force. Increasing the RSO & I capability to clear backlogs in ports and staging areas can be a tool to reduce force vulnerability. [FM 100-17-3]
