Hi.
I just don't understand this secrecy thing. If in another country, the Kub was demobilized - that means it is not a secret anymore. By this rule, the Osa or the Volhov should also be classified because both are in service in some countries... Romania for example which is also a NATO member.
What if someone else .. for example in Russia makes a SA-6 simulator? It has nothing to do with the hungarian government or armed forces, am I right?
