The Patria Pasi is a military armoured personnel carrier. It was the choice of the Finnish Defence Forces to replace its aging Soviet BTR-60s. It was a result of the commercial competition between two Finnish companies, a tractor manufacturer Valmet and the lorry manufacturer Sisu, which won the contract with its prototype.




Prototypes and series


Patria Pasis have been produced in various models for various purposes. Originally Panssari-Sisu, was not produced by Patria, but by Sisu, a lorry manufacturer. The other entry as a possible armoured personnel carrier replacement for the Finnish Defense Force's BTR-60 was Panssari-Valmet, which did not win the competition.
Technically the variants of Pasi are marked with two letters XA, which means cross-country armoured vehicle, the first and second number means the power in tens of kilowatts. Therefore, Pasi XA-180 means that it is a cross-country armoured vehicle (XA) having an engine capable for 180 kW (18× 10 kW). The last number, 0, means that XA-180 is the first version of the 180 kW Pasi's.




Manufacturing companies


The name of the manufacturer has changed several times. Up until 1980, the producer was known as Oy Suomen Autoteollisuus Ab. In 1981, it changed its name to Oy Sisu Auto Ab, which reflected the name of the Sisu branded lorries Suomen Autoteollisuus had manufactured. In 1994, Oy Sisu-Auto Ab purchased Valmet Oy's forest tractor and harvester business, and additionally the production of the tractors and engines. Oy Sisu Ab was founded to function as the holding company of all the new entities and the old Oy Sisu-Auto Ab. For the lorry production, a new Oy Sisu-Auto Ab, now Oy Sisu Auto Ab, was founded.
In 1995, the military vehicle production profit center of Oy Sisu Ab, Sisu Defence is changed into a separate subsidiary company Sisu Defence Oy, which continues the military vehicle production with Masi, Misu, Nasu, Pasi, Rasi and Raisu lorries. In 1996, Sisu Defence was sold to Suomen Puolustusväline Oy, which is a state owned company. In 1997, Sisu Defence Oy merged with Suomen Puolustusväline to become Patria Vehicles Oy.

XA-180EST is the Estonian model of XA-180. The first version was produced in 1983 and serial production began in 1984. The basic design was based on easy usage, simple basic structure and low cost maintenance. The basic appearance and configuration is similar to most wheeled APCs.
There are 58 of them in service, two having been lost in Afghanistan. Finland had sold 61 of them, of which four were medevac models, two command post models and two command and control models. In 2005, there were delivered ordinary ones 30 units and four medevac units. In 2005, 35 units of XA-180ESTs, 2006 21 units and 2007 5 units were transferred to Estonia.
Altogether there were 51 ordinary units, two command and control units, three repair units and four medevac units. The medevac units were equipped with air conditioning and floor heaters. The XA-180ESTs were equipped with Harris radios and 12.7 mm Browning M2 machine guns.
The XA-180ESTs had been manufactured in Finland in 1987–1989 having been used for from 10,000 to 30,000 km. The engine will last about 120,000 to 130,000 km. Ten out of the sixty vehicles have been taken part in the Lebanon peace-keeping operations and the others have been mainly stored or being used in the military training in Finland.
Estonia wanted to buy 30 more XAs from Finland in 2008, but as a part of agreement, Finland wanted them not to be used outside the territory of Estonia, i.e. in the international operations with the coalition of the willing. Therefore, Estonia purchased 81 units of XA-188 from the Netherlands (see below). Also the price was considered to be high for the Estonians.
