(8) The effect-on-system (EOS) codes are used to highlight the subsystem
when a system is NMC because an authorized subsystem is not on-hand. List the
requisition number for the subsystem on the back of the DA Form 2406 and ask the
supporting United States (US) Army Materiel Command (AMC) logistics assistance
office (LAO) for assistance with the requisition. The EOS codes are reported to provide
information on those subsystems which most often fail and cause the system to be NMC.
The EOS codes provide critical data to materiel managers about persistent, recurring equipment
problems which should be focused on and fixed. They are listed as part of the data
supplied in Appendix B-2 of AR 700-138.
