The Supacat is amphibious and has a low ground pressure, enabling it to traverse rough terrain whilst carrying up to eight troops (and two crew), a standard NATO pallet or other stores (ammunition etc.).

In addition, the ATMP in British Army service could be fitted with a MILAN Firing Post.

The Parachute Regiment also conducted a successful proof of concept in 1989 by fitting a Javelin LML to the bed of the ATMP for drop zone air defence.

The Supacat is built around a steel rectangular hollow section chassis frame, which forms the entire shape of the vehicle and to which all components and attachments are fitted.

The 'body' of the Supacat forms a hull that enables the vehicle to float and protects the majority of mechanical components.
