AAL (artillerie antiaérienne légère)

AAL is the French abbreviation for artillerie antiaérienne légère, which translates to light anti-aircraft artillery. The term belongs to French military terminology and describes light artillery intended for air defence, particularly against aircraft and other airborne threats.

The English equivalents are anti-aircraft artillery, light anti-aircraft gun and air defence artillery. NATO places anti-aircraft guns in its wider category of light weapons, and that category gives the French term a clear technical footing. This page explains the NATO classification, the language of the term, and what a Canadian supplier should do when it appears in a document.

How NATO classifies light anti-aircraft guns

NATO describes light weapons as weapons designed for use by two or more people serving as a crew. Anti-aircraft guns with a calibre under 100 mm fall into this group. The description appears in NATO's page on small arms and light weapons and mine action.

Two features define the category in that description: the crew requirement and the calibre ceiling. A gun that needs a crew and measures under 100 mm in calibre is a light weapon. The word légère in AAL points to this lighter end of air defence artillery.

Reading the French term

The abbreviation breaks down into three parts. Artillerie is artillery. Antiaérienne means anti-aircraft, or directed against airborne targets. Légère means light. Together they give AAL, with the letters taken from the first letter of each word.

French and English are NATO's two official languages. NATO's official terminology database, NATOTerm, is maintained by the NATO Terminology Office within the NATO Standardization Office. It holds non-classified military terminology and terminology relevant to NATO in both languages. It is the reference to use when a document requires a precise French and English term pair.

Related terms in English-language documents

A bilingual document may carry the same idea under different names. Look for these related terms:

• Anti-aircraft artillery, the general English term for guns aimed at airborne targets.
• Light anti-aircraft gun, the closest English match for a single AAL weapon.
• Air defence artillery, the broader role these guns serve.
• Light weapons, NATO's category for crew-served weapons under the calibre limit described above.

Canadian spelling uses "defence", and the term "air defence" is spelled that way in Canadian documents. Treat AAL and light anti-aircraft artillery as the same subject when you compare French and English versions of a solicitation.

Where Canadian suppliers find defence and NATO opportunities

CanadaBuys is the Government of Canada's platform for tender notices. It publishes notices from Public Services and Procurement Canada, other federal departments and agencies, Crown corporations, broader public-sector organizations and NATO. Its guidance on searching tender opportunities explains how to filter and find these notices.

Canadian businesses can also reach opportunities from the NATO Support and Procurement Agency through CanadaBuys. The agency buys goods and services on behalf of NATO nations, as described in the guide on how to find tender opportunities. For Canadian defence and security work, the Department of National Defence directs companies to the government's procurement platform to obtain information and submit bids. See its information for companies.

What AAL means for a supplier bidding on Canadian public contracts

Treat AAL as a technical descriptor, not a procurement category. Each solicitation sets its own technical specifications, and those govern what you must supply. When a bilingual notice uses AAL or artillerie antiaérienne légère, read the French and English versions side by side and match the English wording to the same requirement. Use NATOTerm to confirm term pairs, and search CanadaBuys with both the French and English terms so you do not miss notices.
