I take a different view.
I would tend to say that the MUP units were regular, unfiromed, professional police officers, and that they were keenly aware of the Kosovo Verification Team (KVT) presence. I do not believe that they were paramilitary units wearing MUP uniforms! I am sure the exact units involved can be identified if such information were necessary.
I have never heard or read anyone describe Yugoslav Army (VJ) -- whose tanks were allegedly present -- as a bunch of undisciplined, revenge-seeking incompetents.
