The whole world is waiting for Ukraine's counteroffensive. One of those who trained Ukrainian soldiers in this is Major Roger Djupsjö.

He says that it will consist of three important phases. "If you succeed in this, it can happen very quickly," he says. "You want to get inside the opponent's decision circle, which means that every time the opponent makes a decision, it's already too late," says Djups jö. "Then you have exhausted your resources and the units at the front are quite empty"
