In February 2014, street protests in Kiev and other Ukrainian cities led to the ousting of the Russian-backed President Yanukovych. The so-called Euromaidan Revolution saw many changes to Ukraine's constitution, but the violent reaction in the east and south of the country led to armed counter-revolution, unofficially backed by Russia. This conflict is the essential example of Russia's new policy of 'hybrid warfare', which blends propaganda, misinformation, and the deployment of 'deniable' Special Forces and regular troops alongside proxies and mercenaries to achieve its strategic ends. Using his extensive contacts in both Russia and Ukraine, and access to a mass of official and unofficial sources, Mark Galeotti presents a thorough and intriguing primer on all the forces involved in the ongoing conflict in Ukraine. Supported by specially commissioned artwork, he analyses both the progress of the war, and what it teaches us about Russia's current military capabilities.
