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 version 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 Patria Pasi is similar to most wheeled APCs. The XA-180 and XA-185 versions are fully amphibious while the XA-203 is not.
In 1980, Sisu produced an XA-180 prototype for Finnish Army tests. It competed against two other prototypes, but was declared the winner of the trials in 1983. On 22 December 1983 the Finnish Army ordered a first batch of fifty XA-180s, of which nine were reserved for UN duties. The vehicle proved quite successful and more orders were soon to follow.
The XA-180 was originally manufactured and marketed by the Finnish company Sisu Auto but later variants were marketed by the Finnish defence company Patria and are known as Patria XA series. The Vehicle's widely known nickname "Pasi" (also a common given name of Finnish men) stems from the Finnish name "panssari-Sisu" (English: armoured Sisu). The main superstructure is mainly manufactured from 6 to 12 mm of armour steel and the bottom is mine strengthened, the front windows are bullet-resistant and equipped with protective hatches. The vehicle has continuous six wheel drive and good capabilities for off-road driving. It can take inclines up to a maximum of 60°.
The XA series has no standard armament, but is equipped with a rotating turret-structure for installation of light/heavy machine guns or . It also has 8 BMP style firing ports on the sides and rear. Therefore, passengers, usually a squad of infantry, can fire their weapons from the cover of the armor.
The XA series is popular in peacekeeping missions due to its mobility, non-aggressive appearance, and good protection against mines and improvised explosive devices (IED). The vehicle also offers a good combination of armament, comfort, mine protection, protection against shrapnel and small calibre fire, road speed, short time of learning how to drive, and an acceptable terrain mobility. It also offers more internal space compared to other similar vehicles like the Fuchs or BTR-80.
