Hello! Sorry for using english, but my croatian is very bad.
I am working on an Order of Battle (you would say "sastav" or "ustroj", I believe) of former JNA on
www.tank-net.org forum (you can find the original posting there at the military history section). I also have a thread here, but in the politics section.
I hope to be on the right subforum now and to get some additional information.
A first version of the OOB already was published. You can download it here:
