[1/6] The Chair of the NATO Military Committee, Admiral Rob Bauer listens during an interview in Tallinn, Estonia September 16, 2022.
By outlining what it calls its regional plans, NATO will also give nations guidance on how to upgrade their forces and logistics.
Finland's accession last month has alone doubled NATO's border with Russia to some 2,500 km, forcing a more flexible approach to deployments than in the past, when Germany was seen as the main battlezone.
"We don't envision the type of war that the Cold War was, where allied forces ... would be hit simultaneous with large-scale Warsaw Pact attacks," he said, pointing rather to regionalised conflicts that needed to be contained by quick force deployments.
NATO agreed in 2022 to put 300,000 troops on high alert, up from 40,000 in the past.
