Katyusha 122mm multiple launched rocket system mounted on the back of a waggon. A piece of kit little changed from WW2. The Soviet armies loved these and had lots of them - and probably still does.

Not as ally or as advanced as our MLRS, but nevertheless still formidable when a division of the things decides your Shell Scrape is its target.
