Russian state TV has discussed an invasion plan to conquer Baltic states in a chilling broadcast.
A former senior officer spoke about chilling scenario in which Putin's regime captured NATO countries Latvia, Lithuania and Estonia.
It comes as thousands of NATO troops take part in military exercises near the Russian border.
The three Baltic states joined NATO following the break up of the Soviet Union - with fears Putin has plans to destabilise the states and takeover, as he has done in Ukraine.
Colonel Igor Korotchenko, formerly of the Russian General Staff and air force and currently a reserve officer said: “This is how the scenario for capturing the Baltic countries might look."
"Referring to a map, he added: "A massive Russian radio-electronic strike is inflicted" - causing "all Nato radars go blind and see nothing".
Drawing on the map, Korotchenko then turns to how Russia will overpower its foes.

He added: “At this time, on the Swedish island Gotland, Russian military planes land, delivering S-400 anti-aircraft missile systems, and Bastion coastal anti-ship systems."
He continues to explain that the “entire Baltic sea” would then be under target from Russia.
Britain has warned Vladimir Putin that if a "single toecap" of a Russian solider steps into NATO territory "then it would be war".
Health Secretary Sajid Javid said the West had been clear over the response to any aggression on its territory following a bombing near the border with Poland.
The Yavoriv military base was targeted in a deadly barrage of missiles on Sunday, only a few miles from the Polish border.
People were woken by sirens before the “skies turned red” as missiles landed, killing 35 and leaving 134 wounded.
Mr Javid condemned the attack and warned Putin that he could face war with 30 NATO countries if he moved onto their territory.
"If just a single toecap of a Russian soldier steps into NATO territory then it would be war with NATO," he told Sky News.
In another interview he said "it's not impossible" that Russia would launch an attack on Nato territory but he thinks it is "very unlikely".
The UK and other NATO countries have so far resisted sending troops into Ukraine amid fears it could cause a dramatic escalation in the conflict with nuclear-armed Russia.
