ACG stands for amphibious combat group. It is a military term recorded in NATO's glossary of acronyms and abbreviations, where the entry carries the French equivalent groupe de combat amphibie. The glossary is published in English and French, which matches the two official languages used across Canadian defence documents.
The term belongs to NATO terminology. It sits alongside other amphibious acronyms in the same reference and is tied to the NATO Standardization Office terminology framework. Readers who meet ACG in a NATO document, a coalition exercise reference, or a defence briefing can read it as amphibious combat group.
Where the ACG entry appears in NATO terminology
The entry for amphibious combat group appears in AAP-15, the 2013 Glossary of NATO acronyms and abbreviations. The glossary gives the English expansion and the French equivalent side by side. That bilingual format makes it a dependable first check when an unfamiliar acronym turns up in allied material.
NATO also maintains NATOTerm, its official database of non-classified military terminology and relevant non-military terminology. The NATO Terminology Office maintains it within the NATO Standardization Office. For anyone confirming how NATO defines or uses a term, NATOTerm is the authoritative source.
Related amphibious terms in the same glossary
The glossary lists several amphibious terms close to ACG. Reading them together shows how NATO labels different amphibious formations:
- ACG: amphibious combat group (groupe de combat amphibie).
- A/G: amphibious group command.
- ATG: amphibious task group.
These are separate entries. Each acronym stands for its own term, so ACG should not be swapped for A/G or ATG when reading or writing a document.
How ACG compares with Canada's Amphibious Readiness Group
Canadian defence publications discuss amphibious operations, but they use different terminology. A Canadian government military publication refers to an Amphibious Readiness Group (ARG), not an amphibious combat group. The two names are not interchangeable, and the Canadian text does not use ACG.
Another Canadian defence publication describes Canada's amphibious capacity as the ability to put forces ashore where port or airfield infrastructure is limited or damaged. That description explains the operational purpose behind amphibious capability in a Canadian setting, but it does not adopt ACG as a Canadian term.
What ACG means for a supplier bidding on Canadian public contracts
ACG is NATO terminology. The Canadian sources cited on this page use ARG for the amphibious formation they describe, and none of them presents ACG as a requirement attached to a Canadian buyer, a solicitation, or a contract type. A supplier should therefore not treat ACG as a Canadian procurement compliance requirement simply because the acronym appears in NATO's glossary.
Bid teams should do three things in practice. First, read the tender documents on their own terms and follow the vocabulary the buyer uses. Second, if a statement of requirements cites NATO material, check the acronym against the NATO glossary and NATOTerm. Third, keep ACG, A/G, ATG and ARG distinct in proposals so that each term matches the source document it comes from.
