In this episode Dr. Jack Watling, Research Fellow for Land Warfare at the Royal United Services Institute, discusses the conflict between Armenia and Azerbaijan that has erupted since late September surrounding the disputed territory of Nagorno-Karabakh. He examines what we can learn from it about ground combat on the modern battlefield. Among other things, he discusses the saturation of the battlefield with a variety of sensors, challenges associated with electronic warfare, and the importance of camouflage. Collectively, these represent a problem set that the US military and those of its allies largely have not encountered during nearly two decades of military operations in Iraq and Afghanistan—which makes the lessons he discusses especially important.
