Poland sends 40,000 troops to eastern border as Europe moves closer to war with Russia and Putin masses his forces in Belarus for huge Zapad 2025 military drills following drone ‘attack’

Poland has sent 40,000 troops to be deployed on its eastern border as it prepares for Russia and Belarus’s huge spectacle of joint military drills called Zapad 2025.

It comes as Europe is still on high alert following the unprecedented intrusion of Russian drones into Polish airspace this week, with Polish Prime Minister Donald Tusk warning that the West is at its closest to open conflict since World War Two.

He dubbed the upcoming military exercises ‘very aggressive’ and has closed the country’s border with Belarus in anticipation of the intimidating display. 

‘Poland has been preparing for the Zapad-2025 exercises for many months,’ Poland’s Deputy Minister of National Defence, Cezary Tomczyk, told Polsat News television late Wednesday.

‘Polish and NATO soldiers are needed to adequately respond to Zapad-2025,’ he said, adding: ‘This is where the war in Ukraine began. Therefore, the Polish army is preparing for this. In the coming days, we will have about 40,000 soldiers at the border.’

The Kremlin will hold its sabre-rattling Zapad 2025 exercises with Belarus near Poland and Lithuania from Friday until next Tuesday, September 16.

The drills come around roughly every four years. The last, in 2021, led to a massive buildup of forces in Belarus that were used to attack Ukraine several months later.

A former NATO official warned this year’s drills ‘could serve as a cover’ for a military build-up, with tens of thousands of troops expected to attend.

Germany‘s chief of defence Carsten Breuer said that NATO would ‘be on our guard’ around the drills as NATO chief Mark Rutte said Russia was rapidly rearming.

Rutte warned that coordinated attacks from Russia in Europe and China in Asia could trigger World War Three, Putin distracting NATO with an assault in Europe. 

Zapad – meaning ‘West’ – is formally a defensive drill. Troops are expected to prepare repelling an attack, including airstrikes and sabotage, per official reports.

But Russia is expected to bring potentially tens of thousands of troops to rehearse, among other things, using its new nuclear-capable missile on Europe’s frontier.

Some of the drills will take place just a few miles from NATO borders.

Poland is still scrambling to respond to an incursion of 19 Russian drones that crossed over into its airspace overnight between Tuesday and Wednesday.

Tusk invoked Article 4 of the North Atlantic Treaty for the 8th time since NATO’s inception on Wednesday.

It serves as a starting point for major operations and will pave the way for consultations around the perceived threat to territory, independence or security.

The U.N. Security Council will also hold an emergency meeting at Poland’s request to discuss the drone incursion, the Polish Foreign Ministry said on Thursday.

Moscow denied responsibility for the incident, with a senior diplomat in Poland saying the drones had come from the direction of Ukraine, which Russia invaded in 2022.

Russia’s Defence Ministry said its drones had carried out a major attack on military facilities in western Ukraine, but it had not planned to hit any targets in Poland.

With the spectre of war looming over Europe, the Zapad drills come at a precarious time.

Zapad’s organisers say that their drills will not exceed 13,000 personnel, and Belarus has said it will be inviting observers from NATO countries this year.

The actual number of troops is likely to be far higher than 13,000, analysts have already warned.

The Zapad-2021 drills, a prelude to the war in Ukraine, was expected to host 12,800 servicemen; it ended up closer to 200,000, according to Russian authorities.

Satellite images provided by Planet Labs also indicate the construction of a potential military facility in Belarus, according to military analysts.

A site near Minsk, previously used to house Soviet nuclear weapons, appeared in late August to be under redevelopment.

Experts told RFE/RL that they could be used to store ‘strategic level equipment’, including – perhaps – the Oreshnik missile.

‘It is probably going to be nuclear-armed or it will probably be a nuclear component attached to it because they are using the facilities that were already used to house such…equipment during the Cold War,’ Konrad Muzyka, director of the security analysis firm Rochan Consulting, told the outlet.

Lieutenant General (Ret.) Lance Landrum, CEPA Fellow and Former Deputy Chair of NATO’s Military Committee said that this year’s exercise should be compared with the events leading up to the invasion of Ukraine in February 2022.

‘I do think it could serve as a cover. Now we have to look and see what exactly they do in this upcoming exercise, because we have a lot of historical intelligence on previous exercises, and we can compare that,’ he said.

Lt. Gen. Lance Landrum (Ret) added that there would be ‘a lot to be learned here’. For NATO, the drills will offer a window into Russian capabilities and strategies.

An absence of drone activity, crucial for both sides in the war in Ukraine, could indicate Russia lacks the personnel and equipment to train at scale after three-and-a-half years of war.

NATO may also glean insights about Russia’s capacity for electronic interference and jamming. 

Russian and Belarusian forces are expected to practice planning to use the new Russian Oreshnik nuclear-capable missile systems.

Russia’s intermediate-range ballistic missile was used in Ukraine’s Dnipro for the first time last year in what President Vladimir Putin called a ‘test’.

Oreshnik is expensive and makes little sense in Ukraine, where troops are often dispersed across a wide and open front line.

But it does pose a threat to compact targets like air bases – likely first targets in a war with NATO in Europe.

NATO said it will monitor Russia’s activity ‘very closely’, adding ‘we do not see any immediate military threat against any NATO ally’ but ‘we remain vigilant’.

The comment was published days before a drone incursion into Polish airspace overnight between Tuesday and Wednesday pushed tensions to a recent high.

Poland’s prime minister said that the country had identified ’19 violations and shot down at least three drones’, accusing Russia of a deliberate intrusion.

For its part, Russia denied the drones was Russian. The Kremlin said it was a matter for the defence ministry, and accused Warsaw of spreading ‘myths’ to escalate the war in Ukraine. It also offered to hold ‘consultations’ with its Polish equivalent.

Poland was resolute in its assessment. Donald Tusk said there was ‘no doubt that this provocation is incomparably more dangerous … than any previous ones’.

‘This situation brings us all closer to open conflict, closer than at any time since the Second World War,’ he said.

Poland subsequently invoked NATO’s Article 4, under which any member can call urgent talks when it feels its ‘territorial integrity, political independence or security’ are at risk.

The U.N. Security Council will also hold an emergency meeting at Poland’s request to discuss the matter, Poland said.

‘(We are) drawing the world’s attention to this unprecedented Russian drone attack on a member of the UN, EU, and NATO,’ Foreign Minister Radoslaw Sikorski told local radio.

‘I have appeared before the UN (Security) Council in the past, and it seems to me that our arguments have been convincing.’

The West is also holding its own military drills this month. It says the exercises are a ‘response’ to Zapad.

‘Poland will respond to the Zapad 2025 exercises … in an appropriate manner on the Polish side,’ Tomczyk told broadcaster RMF in April.

Iron-Defender-25 will see some 30,000 troops from Poland and NATO allied countries equipped with some 600 units of military hardware take part in exercises by land, air and sea in the Baltic region.

The drills ‘will jointly test their ability to deter and effectively defend the territory of Poland’, a press release from the Polish government says.

Poland’s Armed Forces General Command said the drills began on September 1, a day after the Russian-led Collective Security Treaty Organisation drills began in Belarus.
