LOGDEF (LOGDEFICIENCY (deprecated – déconseillé) logistic deficiency)

LOGDEF is the preferred NATO abbreviation for logistic deficiency. It appears in the NATO glossary of acronyms and abbreviations, AAP-15, where the longer form LOGDEFICIENCY is marked "deprecated" ("déconseillé" in French) and LOGDEF is named as the form to use. The glossary attributes the entry to the NATO Army Standardization Group (NASG). You can read the entry in the 2013 edition of AAP-15.

LOGDEF belongs to NATO's logistics and military-standardization vocabulary. It is a shorthand used in allied documents, and it stands for a deficiency in logistics. Suppliers who work with NATO-aligned defence customers may meet it in standards, specifications or allied correspondence, so it helps to know the correct form.

Preferred and deprecated forms of LOGDEF

The NATO glossary sets out three facts about this entry, and each one affects how you write it:

• The expanded form is "logistic deficiency."
• LOGDEFICIENCY is deprecated, so it should not be used in new writing.
• The preferred abbreviation is LOGDEF.

If you draft documents that use NATO terminology, write LOGDEF and spell out "logistic deficiency" on first use. Do not use LOGDEFICIENCY as a short form.

The NASG attribution

The glossary credits the NATO Army Standardization Group (NASG) with the entry. This places the term within NATO's work to standardize land-force practices and vocabulary across allied nations. The attribution tells a reader which NATO body the entry comes from. It does not by itself make LOGDEF a requirement in any national contract.

Where LOGDEF sits within NATO logistics

NATO describes logistics as an integrated system covering the supply, movement and maintenance of equipment, personnel and services that support operations. It states that logistics can be provided by military, civilian or commercial providers, and that it should be built into the planning and implementation of military operations. NATO sets this out on its page on NATO's role in logistics. A logistic deficiency, and therefore LOGDEF, sits within that supply, movement and maintenance framework.

The mention of commercial providers matters to industry. Companies that supply goods, transport or sustainment services are part of the logistics picture that NATO describes.

Checking NATO terminology in NATOTerm

NATO maintains NATOTerm, its official terminology database. It holds non-classified military terminology and other terminology relevant to NATO. When a document uses an unfamiliar NATO term, NATOTerm is the authoritative place to check it. The AAP-15 glossary remains the source for the specific LOGDEF and LOGDEFICIENCY entry.

What LOGDEF means for suppliers bidding on Canadian contracts

Canadian federal procurement opportunities are published through CanadaBuys, where bid teams search and review tenders. LOGDEF is a NATO glossary term. Each solicitation sets its own requirements and definitions, so read the tender documents for the terms that apply to your bid.

• Use LOGDEF, not LOGDEFICIENCY, when you write about logistic deficiency in NATO-aligned material.
• Spell out "logistic deficiency" on first use so every reader on the bid team understands the abbreviation.
• Check unfamiliar NATO terms in NATOTerm before you use them in a proposal.
