This standard establishes the technical content, style, format, and functionality requirements for all IETMs for major weapon systems and their related systems, subsystems, equipment, assemblies, components, Shop Replaceable Units (SRU), and Line Replaceable Units (LRU). This standard provides requirements for operator and maintenance
technical manuals, Depot Maintenance Work Requirements (DMWRs), National Maintenance Work Requirements (NWMRs), Preventive Maintenance Daily (PMD), Preventive Maintenance Services (PMS), Phased Maintenance Inspection (PMI), destruction of equipment to prevent enemy use manuals, Battle Damage Assessment and Repair
(BDAR) manuals, Preventive Maintenance Checklists (PMCs), Lubrication Orders (LOs), ammunition DMWRs, software manuals, general maintenance manuals, Hand Receipts (HRs), ammunition data sheets, and Technical Bulletins (TBs). The requirements are applicable for all maintenance levels/classes through “overhaul” (depot) including DMWRs and NMWRs. The requirements can be used to develop IETMs for interactive frame presentations.
