Plans are also being drawn up to transport troops via ports in the Balkans, as well as through Norway, Sweden and Finland.

In these corridors, national militaries will not be restricted by local regulations and will be free to transport consignments without normal restrictions.

Previously, the French government has complained that its tanks have been trapped at foreign borders by bureaucratic processes while trying to deploy in Romania as part of a new scheme to defend against a feared Russian invasion.

In the last five years, Jsec has carried out reviews on behalf of Nato to discover various routes that could be used to deliver troops to combat a Russian invasion.

Ports in northern Europe, like the Netherlands, Germany and Baltis states are considered particularly susceptible to Russian missile attacks.

Lt Gen Sollfrank said: “Everything is created in a way so the necessary resilience exists – robustness, reserves and also redundancies.”

But after warnings that Nato only has 5 per cent of the necessary air defences to cover its eastern flank, the Jsec commander is concerned about surface-to-air capabilities to defend his key logistical hubs.

“Observing and assessing the Russian war in Ukraine, we have observed Russia has attacked Ukraine’s logistics bases,” he said.

“That must lead to the conclusion that it is clear that huge logistics bases, as we know it from Afghanistan and Iraq, are no longer possible because they will be attacked and destroyed very early on in a conflict situation.”

“With regards to air defence… It’s always scarce. I cannot imagine a situation that you have enough air defence. That is a good example where a military principle applies: ‘If you want to be strong everywhere, you are strong nowhere.’”
