I wanted to ask about Sevastopol Naval Base, a lot of news agencies are emphasizing Sevastopol as a key strategic base for Russia.
I know it is a very important base for Russian Navy but what happens if ( and it is a big if ) they lose access that base? Strategically would it be so bad to use a different base in Black Sea, such as Sochi or Novorossiysk. TV reporters speak in a way that if Russians dont have Sevastopol, they lose their access to Black Sea.
Novorossiysk is being built as an alternate basing point for the Black Sea Fleet. Construction is far along, and it would be possible to re-base some assets there right now, but the majority would have no home there. Also the scale and scope of the construction there doesn't seem to be sufficient to replace Sevastopol entirely.
Also here's a video of the "polite people" in the Crimean Council of Ministers. The video is from a security camera and has no sound. Their interactions with the police inside seem to be surprisingly calm. The police eventually leave, but come back several times to pick up their stuff. The men in this video do not appear to be regular Russian military.
Their clothing, and equipment in a few cases looks like Russian miltiary, but many of them are wearing civilian attire. The weapons definitely indicate professional military, but they're in many cases customized beyond what even Russian units like SOBR is allowed to do. The PK series machineguns have optics on them and there are at least two (maybe 3). I can't tell if they're PKM or PKP (the latter would suggest Russian military). There is at least one guy with a single-use shoulder-fired rocket (like RPG-22). They carry a tripod-mounted crew-serv. at two points that looks like an AGS-17. Their bearing, equipment, and actions, seem to indicate professional military or paramilitary of some sort. This could be the Crimean militias, with potentially some Russian help. This could be Ukrainian ex-military or ex-law enforcement (like Berkut) that joined the Crimeans. So far information is lacking.

Also here's a video of helicopters flying towards the shut down Belbek military airfield. I count 10 and at least a few are Hinds.There's speculation about whether they're Ukrainian or Russian, but the numbers match up with the Ukrainian claim of 10 Russian helos.
Russian commentators are speculating that some of those helos are Russian Mi-35M, due to the non-retractable landing gear, and the X-shaped tail-rotor. I'll be honest, I'm not so sure. Numbers of Mi-35M are small, and they're usually integrated with Mi-28N units, not Mi-24 units.
Here's a shot from the video where it appears that the Hind is flying with non-retractible landing gear, making it likely an Mi-35M.

Also a Ukranian naval border control (Coast Guard) unit was blocked by Marines from the Russian 810th Marine Bde. The border guards also sighted 10 Russian helicopters traveling into Ukraine. The Marines have blockaded the checkpoint, and set up "snipers" (probably a DM or two with SVDs) around the area.

I would also like to mention, giant (GIANT) Russian military exercises are starting right now, involving over 100 000 troops from the Center and West MD (31st Para-Assault Bde that's supposedly headed to Crimea is in Center MD). In other words it will be very hard to track Russian troops movements with regards to their relevance to the situation in Crimea. This could be a major move, or it could be an implied threat. It could even be both. It could be cover for the smaller number of units being deployed to Crimea. It could even be a regular, planned, large scale exercise, that happened to coincide with this mess.
Also a Russian Black Sea Fleet missile boat is at the entrance to the Balaclava harbor. It's not doing anything from the looks of it. But it has closed down the Ukrainian naval border guards there, from leaving. And ~20 Russian military personnel were seen inside the Balaclava harbor (delivered there by a patrol boat), near the naval border guard unit.

Russian military have also captured GP AeroRukh which control airspace over Crimea. 10-15 were seen there. Metal barriers are set up, and people are instructed not to cross them. Crimean militias are also there.

Over 80 Russian helicopters in West MD have left permanent basing locations and are being rebased to forward positions.

And the Ukrainian Navy headquarters in Sevastopol are blocked by a couple of Ural trucks (probably Russian military). In the trucks are about 40 Russian military service-members.

Photos of Russian military personnel inside Ukraine. To be honest I'm not even sure they have ammo on them...

As do these. The optic is supposedly the Shakhin thermal sight.

And a column of Tigr armored cars followed by Kamaz and Ural trucks, near Sevastopol at night. If all of those are full, this is at least a company+ element. The people filming are saying that the plates on the trucks are Russian. Later on they show a closeup of what appear to be Russian plates, on another army truck in another part of town.
