Combat-proven across the world, all of our AT4 support weapons are lightweight, single-shot and fully disposable.
For any experience level, a dismounted soldier simply aims, fires and destroys the target before discarding the empty tube. AT4 is truly characterised by its ease of use and handling. Our AT4 family is ready for anything, providing the capabilities required for mission success, including night and confined space abilities. The 84mm caliber provides more than sufficient performance when you need it.
Despite different capabilities, from anti-armour and anti-structure to anti-personnel and high-explosive, the family has identical handling and offers maximum versatility.
Saab's AT4 system is one of the most successful anti-armour weapon systems, which can be used against a wide area of targets. Here are some interesting facts about AT4 that you may not already know.
The letters AT were adopted to signify the AT4’s anti-tank capabilities
AT4 is a play on words of ‘eighty-four’, the calibre
More than 1 million AT4's have been produced
The AT4 family is readily deployed by over 15 countries worldwide.

![360 VR Video From 2-8-0 Steam Train Locomotive From 1947 - Pikku-Jumbo - Part 2 of 2
Historical VR Class Tk3 steam locomotive with classic passenger carriages. Traveling from Nokia to Tampere, Finland, easter 2024.
The train is operated by Haapamäen Museoveturiyhdistys ry, Finnish museum train association. More information at https://www.hmvy.fi/.
The Finnish VR Class Tk3 (original classification K5) was a 2-8-0 light freight locomotive. It was the most numerous steam locomotive class in Finland with 161 built. 100 locomotives were constructed between 1927 and 1930, with a further 61 ordered and constructed 1943–53. They were numbered 800–899, 1100–1118, and 1129–1170.

They were designed for a low axle load of just 10.7 tonnes (10.5 long tons; 11.8 short tons). This allowed them to operate on lightly laid secondary lines, but during their many years of service, up to the end of the steam era, they were also widely used on main lines hauling slow passenger trains that made frequent stops.
They were affectionately called Pikku-Jumbo (The Little Jumbo) because of their good performance despite their low weight. They had a low fuel consumption (usually Tk3s used birch wood) and good riding characteristics. They also had good steaming characteristics and were very popular among locomotive crews.
The livery of Tk3 was the same as other VR steam locomotives: dark locomotive green with a black smokebox. When new some locos were lined with thin gold decoration. The gold decorations were not repainted during maintenance, so they were seldom seen.
Two Tk3-type engines were originally supplied by Tampella to Rauma Rautatie as Nos. 9 and 10 (ex-No. 8) in 1935 and 1927 respectively. These engines became Tk3 1117 and 1118 after the private railway was absorbed by the State network in 1950.[1]
Haapamäen Museoveturiyhdistys
Haapamäen Museoveturiyhdistys ry (HMVY) on erikoistunut kotimaisen rautatiekulttuurin säilyttämiseen.
Toiminta keskittyy vanhan rautatiekaluston kunnostus- ja ylläpitotoimintaan Haapamäen Museovarikolla ja museojunaliikenteeseen Suomessa.
Yleistä
Yhdistys on perustettu vuonna 1993 tavoitteenaan säilyttää ja ylläpitää vanhaa rautatiekalustoa sekä siihen liittyvää tietotaitoa. Liikennöimme museojunia eri puolilla Suomea. Yhdistys omistaa Haapamäen veturitallin, vanhan rautatieläisten lepohuonerakennuksen sekä läheisen rautateiden vahtituvan. Yhdistyksen toiminta perustuu talkootyöhon.
Kalusto
Yhdistyksellämme on Suomen suurin ja monipuolisin kokoelma vanhaa rautatiekalustoa eri vuosikymmeniltä höyryvetureista dieselvetureihin sekä puukorisista matkustajavaunuista sinisiin teräskorisiin matkustajavaunuihin. Lisäksi kalustoomme kuuluu useita Dm7 -moottorivaunuja eli Lättähattuja. Liikennöimme museojunia eri puolilla Suomea ja kalustoamme näkyy monissa elokuvissa kuten Marian paratiisi, Kaksipäisen kotkan varjossa ja Hymyilevä mies
Haapamäki Museum Locomotive Association
The Haapamäki Museum Locomotive Association (HMVY) specializes in preserving Finnish railway culture.
The activities focus on the renovation and maintenance of old railway vehicles at the Haapamäki Museum Depot and on museum train traffic in Finland.
General
The association was founded in 1993 with the aim of preserving and maintaining old railway vehicles and related know-how. We operate museum trains in various parts of Finland. The association owns the Haapamäki locomotive depot, the old railway workers rest room building and the nearby railway guardhouse. The associations activities are based on volunteer work.
Vehicles
Our association has the largest and most diverse collection of old railway vehicles in Finland from different decades, from steam locomotives to diesel locomotives and from wooden-bodied passenger cars to blue steel-bodied passenger cars. In addition, our fleet includes several Dm7 railcars, or Lättähattu. We operate museum trains across Finland and our fleet can be seen in many films such as Marian Paradise, In the Shadow of the Double-Headed Eagle and The Smiling Man.
