The NATO chief announced plans to increase the rapid-response unit from 40,000 to 300,000 troops.

The NATO Reponse Force will be transformed and the number of high-readiness forces increased to over 300,000, according to Jens Stoltenberg.

The unit was activated for its first collective-defense mission one day after Russia invaded Ukraine.

Sky News' Deborah Haynes reported that NATO's defense units have been restructured since the cold war.

The plan will be agreed at the NATO summit in Madrid later this week, according to reports.
