Interesting, a bit of Nork kit I had no knowledge about, and apparently being used now by Russia in penny numbers?

Bulsae-4 - I wonder what versions 1-3 were, possibly the local name for the regular BRDM sagger, spandrel etc. units?.
An NLOS missile for the Norks? - whoda thunk it

!
Edit - the "bulsae" name appears to be the missile name and not the carrier. I know it's wiki, but a starting point for research:
https://en.wikipedia.org/wiki/Bulsae_ATGM
So the name is for the missile and not the carrier vehicle. end edit
