[Kazuaki Shimazaki II]

OK, I've been waiting for one of these threads to get some questions about the Russian personnel systems (that I got from reading the Kursk crew rosters) aside. You have access to Russian subs that most of us can only dream, but I'm still asking some pretty rare stuff, so feel free to answer only those you feel you can:

The Divisional Staff:
If possible a listing of the all the more important posts in a Russian naval diviziya leadership would be nice, but otherwise:

1) Who was senior in position, K2R Belogun, a "deputy chief/заместитель начальника электромеханической службы" or K2R Isayenko, an "assistant to chief/помощник начальника электромеханической группы". What are the differences in their duties, since in English they sound almost synonymous.

2) What is a "temporary acting torpedo flag officer/[/COLOR][COLOR=white]ВрИО флагманского специалиста БЧ-3"? Doesn't "acting" already mean temporary? What's missing in this usual translation?

Compartment 2/the CCP team
3) K2R Dudko was born in 1969, so he was about 31 or 32, a very young age for a full Commander's equivalent and XO of a 1st Ranked Vessel. According to Suvorov/Rezun, there are minimum periods of service in each rank before a person can be promoted in the Soviet ARmy. Is this practice shared in the Russian Navy? Is Dudko just particularly young, is his youth a sign of the officer shortage in the Russian Navy, or were K2R's always that young even in the Soviet Navy days?

4) Does "survivability division commander/командир дивизиона живучести" mean "damage control officer"?

5) What does BCU-7/БЧ-7 ("combat control") do?

6) According to Truscott, the BCU-3 (torpedo) commander of Kursk should have been a K2R, which sounds reasonable. Are all other BCU commanders (from 1-7) supposed to be filled by Captain 2nd Ranks (we all know that lofty goal was not attained)?

Even counting in an officer shortage, how did 23-year old Senior Lieutenant Ivanov-Pavlov get to sit in that lofty position (no matter how good his grades were at school) on what seems to be his first crack out of the box? Is this kind of thing unique?

Compartment 3
7) What is a "помощник командира" (Repnikov)? He is not the XO or a deputy, but is still relatively senior. By "assistant", does it mean "secretary"?

8) What happened to BCU-6? I never saw it on any list?

9) How are officers of the watch selected on a Russian Navy sub, and how many would there be?

Thank you.
