The Multi-Mission Effects Vehicle (MMEV) was a dual-purpose short range surface-to-air and anti-tank platform intended for use by the Canadian Forces.

It was based on Air Defense Anti-Tank System (ADATS) technology, and integrated onto an 8×8 wheeled LAV III.

Prime contractor for the first, $100M phase of the project was to be Oerlikon Contraves Canada.

The MMEV was designed with a full ISTAR platform, enabling it to communicate with NATO and Tri-Services of the Canadian Forces.
