>>1551199This is not division 990II, but the internal military unit number for military base 99011, which is located in Severomorsk, Murmansk Oblast. I don't understand who BPИO lieutenant colonel is, Пeйo(y/p)? In any case, it was silly to ask here. You're going to need to go to
forumavia.ru and ask there. Many ex-USSR military personnel visit it, as well as people with connections to air units.
