You're full of it Russkie:
"The National Guard of Ukraine (NGU; Ukrainian: Національна гвардія України, Natsionalna hvardiya Ukrayiny) is the reserve component of the Armed Forces of Ukraine under the jurisdiction of the Ministry of Internal Affairs"
http://en.wikipedia.org/wiki/National_Guard_of_Ukraine
It is NOT an illegal, unofficial army, Russkie.
The Right Sector and Kolomoisky Militias do not answer to the Army, either. Even the Kiev-1 and -2 battalions are paramilitary, and outside of the Army chain of command.
Kiev-1 and 2 are special battalions under the control of the Interior Ministry, and, hence, the National Guard. The Azov battalion, whom you call a "Right Sector" outfit, was authorized by Ukraine and are under the control of the Interior Ministry. It has not been associated with any alleged human rights abuses. Who are these "Kolomoisky Militias" you are talking about? Provide sources. Does this mean that there aren't any local militias working independently? No, but this doesn't make the National Guard somehow an independent army under personal control of a civilian, and that it's okay for the Russkies, as a matter of standard operating policy or their entire military, to torture and humiliate Ukrainian POWs.
This disunified command has caused MANY problems for Kiev, with different, often competing, political and military goals
They seem to be doing pretty well Russkie. I don't think the Russkies intended to be fighting this war for so long.
I am really stunned that you still continue with the fiction about the Right Sector battalions, even the OSCE has begun calling them out, specifically.
The OSCE mentions only the Aidar battalion, made up mostly of natives from Donetsk, for alleged bribery and abductions (aka arrests) of alleged separatists. Not executions; nor does this extend to all of the battalions or the Ukrainian armed forces as a whole.
lol...
You try SO HARD to deny the facts already in evidence.
Why??
