FLS2 (forward logistic site)

FLS2 stands for forward logistic site. It is a location positioned forward in an operational area to support logistics. NATO's glossary of acronyms and abbreviations lists the entry as "FLS2, forward logistic site" and attributes it to Allied Logistics Publication 11 (ALP-11). The French equivalent is site logistique avancé.

The term belongs to NATO logistics terminology. Canadian suppliers who work on defence and allied-operations requirements may meet it in NATO documents, in the abbreviation lists attached to them, or in related material. The numeral is part of the abbreviation and should be kept when the term is written or quoted. This page sets out what the term means, where it comes from and how it relates to similar terms.

How NATO's abbreviation glossary records FLS2

The entry for FLS2 appears in AAP-15 (2013), the Glossary of NATO acronyms and abbreviations. The glossary is bilingual, so each English expansion is paired with its French equivalent. For FLS2 the English expansion is forward logistic site and the French is site logistique avancé.

The entry also names its source publication, ALP-11. That citation tells a reader which NATO logistics publication the abbreviation comes from, and it is the reference to use when a document needs to show where the term originates.

NATO's official terminology database is NATOTerm, which is maintained by the NATO Terminology Office. It is the place to check NATO-approved terms and their official wording. NATOTerm is available through the NATO Standardization Office portal.

FLS2 compared with FLS1 and FLS

The same glossary lists FLS1 as "field landing strip." FLS1 and FLS2 share the same letters, and only the numeral separates a landing strip from a logistic site. A writer who drops the numeral creates an ambiguous abbreviation. Proposals, technical documents and correspondence should therefore always write the full abbreviation with its numeral, and spell out the expansion on first use.

• FLS1: field landing strip.
• FLS2: forward logistic site.
• FLS: Forward Logistics Site, as expanded in the NATO Logistics Handbook.

The handbook uses the unnumbered form FLS for the same concept. The glossary and the handbook agree on the meaning, so a reader who finds either form in NATO material can treat both as forward logistic site. The spelling differs slightly: the glossary writes "logistic" and the handbook writes "Logistics."

Forward logistics sites in the NATO support network

NATO operational material uses the plural expression forward logistics sites as one element of a joint logistics support network. In a 2022 SHAPE news item on a technical arrangement between Joint Force Command Norfolk and the Norwegian Defence Logistics Organisation, they appear alongside several other elements:

• points of debarkation
• lines of communication
• logistic bases
• convoy support centres
• staging areas

This places the forward logistic site within a wider set of locations and routes that move and sustain forces. The site is the forward point in that arrangement, positioned in the operational area it supports.

What FLS2 means for suppliers bidding on Canadian public contracts

For a bid team, FLS2 is a term to read correctly, not a procurement category. If it appears in a solicitation, annex, statement of work or abbreviation list, read it as NATO's forward logistic site and check the requirement text around it. The solicitation itself sets out what is being bought and what the supplier must deliver.

Write the abbreviation with its numeral and give the full expansion on first use, so evaluators do not confuse it with FLS1. When a document cites ALP-11, treat that as the NATO reference for the term.

To find federal opportunities that mention logistics support, use the tender notices, contract awards, standing offers and supply arrangements published through CanadaBuys procurement and contracting data. Search on the spelled-out term as well as the abbreviation, because buyers may write either form.
