ACMAT (Ateliers de Construction Mécanique de L'Atlantique, also known as ALM-ACMAT), is a French producer of cross-country and tactical military vehicles since 1958. Known for their reliability, simplicity, ruggedness and their 80% (over 3,500) commonality of parts across the entire product line, these vehicles were originally targeted at African and Asian countries who could not afford more expensive vehicles. The ACMAT company built their vehicles based on standardisation, commonality of parts and components, and on interchangeability; parts are interchangeable with vehicles built 30 years ago. Parts commonality includes cabs, structural components, engines and drive trains. ACMAT uses many of the same parts for all of its line of vehicles. They even produce an armoured variant of both the 4x4 and 6x6 versions of the VLRA.
Many French fire brigades also use ACMAT vehicles due to their lower cost and 4WD ability. Several thousand are in use by 42 countries including France and the Irish Defence Forces. ACMAT also designs, manufactures and builds trailers, shelters and generators. ACMAT has exported over 85 percent of the 12,000 plus vehicles it produced into 50 different countries.
As of 22 May 2006, ACMAT is a wholly owned subsidiary of Renault Trucks.
