I just read some article from
https://en.defence-ua.com/weapon_and...ine-11351.html and NK has also other version of
Bulsae-4 M-2022 installed on small truck 6x6 which rather wasn't sent to Russia.
And since 2016 also
Bulsae-4 mounted on Mi-2 helicopters. That is interesting story about Mi-2 in NK. They were imported from Poland in parts and are know locally as
Hyŏksin-2. First appears in 1977 in the DPRK unarmed then were fitted with four 4x 9M14 Malyutka (Bulsae-1) 1980-1984 manufactured. Insted of Malyutka they can carry two 57mm UB-16 rocket pods or 4 Malyutka & and two 57mm pods. And now Malyutka were exchanged to Bulsae-4.
