(Reuters) - The career of Sergei Yeliseyev helps to explain why Ukraine's armed forces gave up Crimea almost without a fight - and why NATO now says it is alert to Russian attempts to undermine military loyalty in its eastern European members.

His rise to become number two in the Ukrainian navy long before Russia seized Crimea illustrates the divided loyalties that some personnel in countries that once belonged to the Soviet Union might still face.

Yeliseyev's roots were in Russia but he ended up serving Ukraine, a different ex-Soviet republic, only to defect when put to the test. NATO military planners now believe Moscow regards people with similarly ambiguous personal links as potentially valuable, should a new confrontation break out with the West.

In 2014, Yeliseyev was first deputy commander of the Ukrainian fleet, then largely based in Crimea, when Russian soldiers in unmarked uniforms took control of Kiev's ships and military bases on the peninsula.

Instead of resisting, Yeliseyev quit and subsequently got a new job: deputy chief of Russia's Baltic Fleet.

Yeliseyev, now aged 55, did not respond to Reuters questions sent to him via the Russian defense ministry.

In Kiev, however, there is no doubt where his loyalties lay. "When he took an oath to Ukraine, these were empty words for him. He has always been pro-Russian," said Ihor Voronchenko, now commander of the Ukrainian navy, who once served with Yeliseyev.

In fact, the Russian soldiers were pushing at an open door in late February 2014 - Yeliseyev was just one of many to defect and almost all Ukrainian forces in Crimea failed to resist.

Russia annexed Crimea the following month, prompting a major row with the West which deepened over Moscow's role in a rebellion in eastern Ukraine that lasts to this day.

At the time, Moscow and its allies in Crimea exploited weaknesses within Kiev's military to undermine its ability to put up a fight, according to interviews conducted by Reuters with about a dozen people on both sides of the conflict.

The Russian defense ministry did not respond to questions on their accounts of the events in 2014 submitted by Reuters.

One NATO commander told Reuters that, in a re-run of the tactics it deployed in Crimea, Russian intelligence was trying to recruit ethnic Russians serving in the militaries of countries on its borders.

Speaking on condition of anonymity, the commander said the alliance was particularly sensitive to the risk in countries with high concentrations of ethnic Russians, notably the Baltic states.

NATO had to guard against this, said the commander, though the risk should not be overstated because having Russian roots did not necessarily mean that a person's loyalty is to Moscow.

Officials in the Baltic states, former Soviet republics which unlike Ukraine are NATO members, play down the danger.

NATO Secretary-General Jens Stoltenberg likewise said he trusted the armies of the Estonia, Latvia and Lithuania. Still, he told Reuters: "We always have to be vigilant. We always have to develop our intelligence tools and to be able to see any attempts to try to undermine the loyalty of our forces."


Years before the Crimean annexation, a Ukrainian appointment panel appeared to drop its guard when it interviewed Yeliseyev for the deputy naval commander's post.

Yeliseyev was born near Moscow, graduated from a Soviet naval school in the Russian city of Kaliningrad in 1983 and served with the Russian Pacific fleet.

So the panel asked Yeliseyev what he would do if Russia and Ukraine went to war. He replied that he would file for early retirement, according to Myroslav Mamchak, a former Ukrainian naval captain who served with Yeliseyev. Despite this response, Yeliseyev got the job in 2006.

Mamchak did not disclose to Reuters how he knew what was said in the interview room but subsequent events bear out his account.

Relations between Russia and Ukraine dived as Kiev moved closer to NATO and eight years after his appointment, with the countries on the brink of conflict over Crimea, Yeliseyev stayed true to his word by quitting.

Russia's actions were not the only factor in the Crimean events. Ukraine's military had suffered years of neglect, there was a power vacuum in Kiev after the government was overthrown, and many Crimean residents felt more affinity with Moscow.

Still, Ukrainian service personnel with Russian ties switched sides when the annexation began and some officers pretended to put up resistance only to avoid court-martial. Moscow also intercepted orders from Kiev so they never reached the Crimean garrison.

"There was nothing spontaneous. Everything was organized and each fiddler played his role," said Mykhailo Koval, who at the time was deputy head of the Ukrainian border guard and is now deputy head of the Security Council in Kiev.


Voronchenko, who was another deputy commander of the navy at the time of the annexation, said he had received invitations to defect to Moscow's side soon after the Russian operation began.

These, he told Reuters, came from Sergei Aksyonov, who was then head of Crimea's self-proclaimed pro-Russian government, as well as from the commander of Russia's southern military district and a deputy Russian defense minister.

Asked what they offered in exchange, Voronchenko said: "Posts, an apartment ... Aksyonov offered to make me defense minister of Crimea." Neither Aksyonov nor the Russian defense ministry responded to Reuters questions about the contacts.

Voronchenko, in common with many other senior Ukrainian officers, had been in the Soviet military alongside people now serving in the Russian armed forces. He had spent years in Crimea, where Russia leased bases from Ukraine for its Black Sea fleet after the 1991 break up of the Soviet Union.

"Those generals who came to persuade me ... said that we belong to the same circle, we came from the Soviet army," he said. "But I told them I am different ... I am not yours."

Naval chief Denis Berezovsky did defect, along with several of his commanders, and was later made deputy chief of the Russian Black Sea fleet.

Many in the ranks followed suit. At one Ukrainian signals unit, service personnel were watching Russian television when President Vladimir Putin appeared on the screen.

"To my surprise, they all stood up," said Svyatoslav Veltynsky, an engineer at the unit. "They had been waiting for this." The majority of the unit defected to the Russian side.


Even those willing to resist found themselves in a hopeless position. One member of the Ukrainian border guards told Reuters how his commander had despatched their unit's ships to stop them falling into Russian hands, and ordered his men to train their rifles on anyone trying to enter their base.

However, the base's military communications were not working, having been either jammed or cut by the Russians. Isolated from his own side, and outnumbered and outgunned by Russian troops outside, the commander struck a deal with the head of a Russian special forces unit.

Pro-Russian civilians were allowed to force the base's gate without reprisals. The Ukrainians "supposedly could not do anything; you cannot shoot civilians", the member of the unit said on condition of anonymity because he is still living in Crimea and feared repercussions.

Russian troops then followed the civilians in, taking over the base and offering the unit a chance to switch allegiance to Russia. About half agreed, although the base's chief refused and was allowed to leave Crimea.

"The commander did not resist," said the unit member. "On the other hand, he did what he could under the circumstances."

Two other people involved in the annexation - a former Ukrainian serviceman now on a Russian base in Crimea, and a source close to the Russian military who was there at the time - also described witnessing similar faked confrontations.

"You have to understand that the seizure of Ukrainian military units in Crimea was just a show," said the source close to the Russian military.

Why Ukrainian forces gave up Crimea without a fight - and NATO is alert | Reuters

Admiral Sergei Eliseyev

Admiral Denis Berezovsky, who had attended training drills with US, among others, btw

During the Crimea crisis, he appeared in a video with Sergei Aksyonov, the new Russian governor

where he pledged allegiance to the people of Crimea and Russia, and also urged all the men under his command to do same.

He also visited his Naval and Marine bases and convinced them to surrender peacefully to the Russians

Many Ukrainians still can't believe he defected. He was previously known as a staunch Ukrainian patriot, a relatively young officer, from Kharkov, one of very few officers there, in Crimea, who actually spoke Ukrainian fluently; and also was educated abroad and spoke English, which is why he got sent to the Sea Breeze Exercises with the US... Very unexpected, in short.

The interesting thing is that, back in 1991-2, when the Soviet Black Sea Fleet in Crimea was divided between Russia or Ukraine; there were no loyalty issues. It was pretty clear: you either wanted to serve Russia or Ukraine, one or the other. Yes, ship crews were far from unanimous. Fist fights broke out abroard often enough, over which flag to raise instead of Soviet: Russian or Ukrainian. Sheer numbers decided all. Where Russians were majority, the pro-Ukrainian sailors left and the ship became Russian, and vise versa. Ukrainians who wanted to serve Ukraine were roughly a third of the Fleet's personnel. So, Ukraine got about a third of the ships too. All fair

The early years were marked by a clear rivalry between the two BSFs, Russian and Ukrainian.

However, as time went by, I believe this got smoothed over. Many of the officers went on living and serving side by side there for many years. Old Soviet era friendships were rekindled. Their children married each other, in many cases.

And, especially in recent years before 2014, under Yanukovich, the relatively pro-Russian President really gave Russia a free hand in Crimea. Including their spies.

I have no doubt the Crimea operation was planned years ahead. It wasn't just the Ukrainian Navy and other military units in the area, who were infiltrated and neutralized from the inside; along with Ukrainian police forces in the area, many of whom defected right away, including the special unit Berkut (Falcon), ordered to disband by new Ukrainian government over accusations of brutality at Maidan, but who, instead, the entire unit, switched sides, set up armed checkpoints on the border between Crimea and mainland Ukraine

and even provided their uniforms to Russian troops, so that, initially, they could blend in and operate secretly, pretending to be local forces; though, later, they openly wore their own gear over the Berkut unis, when they no longer needed to hide who they are

But even the regional office of the SBU, the Ukrainian national security and counterintelligence agency, was compromised as well. I read letters from a Ukrainian SBU officer from Crimea, which he wrote to Kiev before 2014 (and published later), where he lamented that pro-Russian sympathizers filled most powerful positions in the Crimean detachment of SBU. He mentioned an episode, where, finally, Kiev ordered a raid on a radical pro-Russian party suspected of disruptive activities (led then by Mr. Aksyonov, the Governor now, btw lol), only for a high ranking regional officer to call those guys and warn them, ahead of the raid, enabling them to hide or destroy any evidence against them. He also mentions the Russians openly handing out their passports to Crimeans for years; Russian government propaganda filling up the media in Crimea; etc. The regional SBU, led by pro-Russian officers, did absolutely nothing about this too.

Many of those officers stayed on, when SBU Crimea became FSB Crimea. Though, they are, of course, now excluded from the more sensitive positions. The Russians are not especially trusting of traitors, even those on their side The appointment of those Ukrainian Admirals to Russian Fleets also met with some controversy for that same reason...

But, anyway, yeah, this is definitely something for others in the ex-USSR to learn from.
