For centuries, leaders often depended on bands of mercenary warriors to make up their military strength in times of war, but as national militaries evolved, these formations shank from prominence, with modern PMCs generally being focused on support roles like base or VIP security or logistics (even if their contracts grew massively post 2001). Wagner doesn't follow that example. A force tens of thousands strong, Wagner has helped spearhead the Russian offensives around Bakhmut, and taken on international prominence. In this episode, I look at the evolution of PMCs, Russia's modern employment of them, and the implications of Wagner's role in Ukraine and its public spats with the Russian MoD.
