Title:  Preparation of Digital Technical Information for Technical Manuals (TMs)
Scope:  This standard establishes the technical content, style, and format requirements for all Technical Manuals (TMs) and publications for major weapon systems and their related systems, subsystems, equipment, assemblies, components, Shop Replaceable Units (SRUs), and Line Replaceable Units (LRUs).

This standard provides requirements for operator and maintenance technical manuals, Depot Maintenance Work Requirements (DMWRs), National Maintenance Work Requirements (NMWRs), 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, and general maintenance manuals, Hand Receipts (HRs), ammunition data sheets, and Technical Bulletins (TBs).

The requirements are applicable for all maintenance levels, including DMWRs and NMWRs. The requirements in MIL-STD-40051E should be used to develop maintenance technical and equipment publications regardless of output. The terms "IETM" and "ETM" to refer to output-specific requirements when necessary. When the text does not specify whether a requirement applies specifically either to ETMs or IETMs, the requirement applies to both outputs.
