We brougth some surplus Dutch M249 launchers while back ago, but I think the BM-21 lineage equipment is now retired or atleast in reserve.
First they are called M270(MLRS). Second they weren't surplus. The Royal Dutch Army sold them because of cuts in the Defence Budget.
When I searched pictures on the internet for the RM-70/85, I also found some of finnish RM-70/85 in not perfect condition, seeming beeing some where stored or (waiting for scrapping?).
No they are still in service.
