Major Roger Djupsjö works at the Swedish Armed Forces' headquarters planning major exercises and has previously worked in Ukraine.
How the country handled the attack from Russia is now being analyzed.
- Ukraine is very successful.
Who would have thought that a small country like Ukraine, which has the 28th military power in the world, could stand up to the second largest military power in the world, says Djupsjö.
Everyone must have a task
In addition to military strategies, the civilian side has also proven to be of great importance to the successes.
Not only those who support the military in healthcare and logistics, but that all citizens are given the opportunity to contribute in a small way.
- Instead of just sitting at home and enduring, you have something to do.
It helps you put up with the horrific experiences you have, quite simply, says Roger djupsjö.
