Essential Function 5 - Force Sustainment

"EF 5 aims to sustain the Afghan Force through effective facilities management, maintenance, and medical and logistics systems. Current sustainment processes lack uniformity across echelons and between MoI/ANP and MoD/ANA. Areas for improvement include capturing demands, managing assets, and management reporting and decision-making. Success for EF 5 is achieved when ASI/ANSF have institutionalized a management culture based on proper stewardship and husbandry of capability." 1.

Overview of Essential Function 5

"Essential Function 5's mission is to advise, train, and assist Afghan Minitries of Interior and Defense and the individual Train Advise and Assist Commands (TAACs) to build logistical and maintenance capacity and capability in the fields of logistics and maintenance; medical; and information, communication and technology. EF4 is an organization within the Deputy Chief of Staff for Support and the Resolute Support Mission . . . " 2.

Desired Essential Function 5 End-State

"Afghan Security Institutions / Afghan National Security Force capable of providing at all echelons effective logistics, medical, and information communication and technology support, which sustains required ANSF operational capability within available resources." 2.

Sub-Sections of EF 5. There are three sub-sections of EF 5. 2.

EF 5.1 advises and assists the ANSF in logistics and maintenance of vehicles, equipment and weapons at the Corps and national levels. It also advises senior officers and civilians within the security ministries. One example of EF 5.1 is the assistance provided to the Afghans which enables them to properly utilize computerized inventory management systems. The use of these systems help the Afghans manage inventory and fill reorder requirements for supplies, material, ammunition, and parts. A computerized inventory management system assists the Afghans in running an efficient and cost effective "demand based" supply system. Life cycle management is another aspect of logistics and maintenance in which the EF 5 advisors are assisting the Afghans. For instance the development of and adherence to a national maintenance strategy ensures the longest possible life of equipment provided to the Afghans through the Foreign Military Sales (FMS) system.
