The Fabian strategy is an approach to military operations where one side avoids large, pitched battles in favor of smaller, harassing actions such as skirmishes to cause attrition, disrupt supply and affect morale. It is generally adopted by smaller, weaker powers when combating a larger foe in order to break the enemy's will to keep fighting and wear them down through attrition.1 Skillfully prosecuted this type of strategy proffers an opportune opportunity to defeat a superior foe in a conventional trial of arms.
Like I said, nothing to do with defending by digging in heavy defenses. Ukraine has simply refused to give up territory, fighting for every inch, that's the "strategy" and this has not only been the reality, the puppets in kivv have repeatedly said that much.
