I could write something relatively in-depth over time, but is it instead better to describe events in broad strokes? E.g. the initial advance, then the beginning of Phase 2 by Russia, Mariupol and Severodonetsk being taken, Kharkov, Kherson, Bakhmut, Ukraine's current counteroffensive?
General descriptions could fit in the initial paragraphs and sections, but you can make deeper descriptions on later sections or even add further sections
