Viktoriya Fedorchak introduces her new book "The Russia-Ukraine War: Towards Resilient Fighting Power". She provides an outline of the book and its findings along with a more detailed discussion of fighting power and resilience as concepts. Viktoriya talks about the impact of the Soviet heritage on the preparations for war in Ukraine and Russia when it comes to artefacts, doctrines and reforms, and offers an account of how Ukrainian resilience and fighting power were mirrored in the land, air and sea domains during the first war of the Russian full-scale invasion of Ukraine.
