Another thing.
In the table of equipment, there is the SA-8a listed and available from 1980 to 1992. True or not, I've seen SA-8b on parade in 2004 and I believe they are still in service today.
Romanian SA-8b in 2004
Also missing from the table of equipment is the SA-3. But unfortunately I have no dates. All I know is that Elmec (
www.elmec.ro) provides safety systems for firing SA-3 among other SAM missiles.
