United States Military Standard
A United States defense standard, often called a military standard, “MIL-STD”, “MIL-SPEC”,
or (informally) “MilSpecs”, is used to help achieve standardization objectives by the U.S.
Department of Defense.

Standardization is beneficial in achieving interoperability, ensuring products meet certain
requirements, commonality, reliability, total cost of ownership, compatibility with logistics
systems, and similar defense-related objectives [1].

Defense standards are also used by other non-defense government organizations, technical
organizations, and industry. This article discusses definitions, history, and usage of defense
standards. Related documents, such as defense handbooks and defense specifications are
also addressed.

Definition of document types

Although the official definitions differentiate between several types of documents, all of these documents go by the general
rubric of “military standard”, including defense specifications, handbooks, and standards. Strictly speaking, these documents
serve different purposes. According to the Government Accountability Office (GAO), military specifications “describe the
physical and/or operational characteristics of a product”, while military standards “detail the processes and materials to be
used to make the product.” Military handbooks, on the other hand, are primarily sources of compiled information and/or
guidance. The GAO acknowledges, however, that the terms are often used interchangeably.

Official definitions are provided by DOD 4120.24-M Defense Standardization Program (DSP) Policies and Procedures, March 2000, OUSD (Acquisition,
Technology and Logistics):

Acronym Type Definition

MIL-SPEC Defense Specification A document that describes the essential technical requirements
for purchased materiel that is military unique or substantially
modified commercial items. MIL-STD-961 covers the content and
format for defense specifications.
