When Russia invaded Ukraine last year, its ground forces were largely built around the battalion tactical group. Fifteen months on, and that organizational structure has been dramatically changed. Why? And what explains other examples of evolving Russian tactics? Dr. Jack Watling, a senior research fellow for land warfare at the Royal United Services Institute, joins this episode to address these questions and examine these adaptations. He recently coauthored a report, based on close and firsthand study of the war in Ukraine, that traces a number of the specific ways in which Russian tactics have changed over the course of the conflict. He describes those adaptations in this conversation—and explains their implications for Ukraine and its international supporters.
