The different lines (distances) are essential for logistics planning and operation. An LRU is usually a sealed unit such as a [[radio]] or other auxiliary equipment. LRUs are typically assigned logistics control numbers (LCNs) or work unit codes (WUCs) to manage [[logistics]] operations.

LRUs can improve maintenance operations, because they can be stocked and replaced quickly from distributed on-site inventoryinventories, restoring the systemmobile systems to service, while the failed (unserviceable) LRU is undergoing maintenance most often in off-site support locations. Because theyof aretheir modularmodularity, theyLRUs also reducecan contribute reducing system costs and increase quality, by centralizing development across different models of vehicles.<ref>[http://stinet.dtic.mil/oai/oai?verb=getRecord&metadataPrefix=html&identifier=ADA201577 A Cost Trade-Off Analysis of F-16 Line Replaceable Unit (LRU) Packaging Options<!-- Bot generated title -->]</ref>
