The Patria Pasi (earlier known as the Sisu Pasi) is a Finnish-made six-wheeled armoured personnel carrier (APC) originally designed for Finnish Defence Forces. The first variant was produced in 1983 and serial production began in 1984. It was designed to operate with ease of use, simple structure and low-cost maintenance. The basic appearance and configuration of the Pasi is similar to most other wheeled APCs. The XA-180 and XA-185 are fully amphibious, while other variants are not.
