It's not "mortar" and it's a Soviet production. Everyone in this war captured massive quantities of post-Soviet weaponry from the other side, including Russia already in early 2014 when their irregulars overrun most of Donetsk and Luhansk oblasts including military depots (one was Europe's second greatest storage of small arms in a salt mine) with only token or just no resistance.
It wasn't any "mortar" and you just made up shit as you always do.

You are very easy to be misled about things you know nothing about.
