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.
An armoured train or armored train is a railway train protected with heavy metal plating and which often includes railway wagons armed with artillery, machine guns, and autocannons. Some have also had ports used to fire small arms from the inside of the train, especially in earlier armoured trains. For the most part, they were used during the late 19th and early 20th centuries, when they offered an innovative way to quickly move large amounts of firepower into a new location. Most countries have discontinued their use – road vehicles became much more powerful and offered more flexibility, train tracks proved too vulnerable to sabotage and attacks from the air, and air transportation was an even more flexible way to relocate firepower to a new location. However, there have been occasional uses in the late 20th century and early 21st century. The Russian Federation has used improvised armoured trains in the Second Chechen War (1999–2009) and in its invasion of Ukraine (2022–present).

An improvised fighting vehicle is an ad hoc combat vehicle resulting from modified or upgraded civilian or military non-combat vehicle, often constructed and employed by civilian insurgents, terrorists, rebels, guerrillas, partisans, drug cartels, criminal organizations or other forms of non-state militias and irregular armies. Such modifications usually consist of grafting improvised armour plating and fixed crew-served weapons such as heavy machine guns or antiaircraft autocannons mounted onto the back of a utility vehicle or pickup truck.

Pro-democratic and pro-Ukrainian partisan movements have emerged in Belarus and Russia following the Russian invasion of Ukraine, a major escalation of the Russo-Ukrainian War. These resistance movements act against the authoritarian governments of Alexander Lukashenko in Belarus and Vladimir Putin in Russia, as well as against civilian supporters of these authorities and the armed forces of both countries, with the aim of stopping the war.
The rail war began in different regions of Russia in the spring of 2022 after a similar rail war in Belarus.
The Russian armoured train Volga is an armoured train currently in use by Russia in its ongoing invasion of Ukraine in 2022. Unlike its sister train Yenisei, which is built primarily for logistics and refugee ferrying, Volga is primarily used for engineering, reconnaissance, mine clearance, restoration of damaged railway tracks, and escorting cargo within the Ukrainian combat zones.
The Russian armoured train Baikal is an armoured train currently in use by Russia in its ongoing invasion of Ukraine in 2022. Unlike the newer trains Yenisei and Volga, Baikal was already built long before the Russian invasion of Ukraine. Both Baikal and its sister train, Amur were reactivated back in 2016, originally for rear-line logistical purposes.
