Hello everyone,

I urgently looking for technical information (not the generally accessible information from the Internet) about the Russian cluster bombs RBK-500 (РБК-500) and RBK-500U (РБК-500У)
and it´s submunitions PTAB-1 (Кассетная бомба ПТАБ-1), PTAB-1M (Кассетная бомба ПТАБ-1М and their fuzes PIBDSD D-683 (Д-683) / D-684 (Д-684) and D-684-1 (Д-684-1).)
The best would be copies or extracts from the original regulations.

Thank you in advance.
