Former British Army officer Lieutenant General Doug Chalmers — who served as Deputy Chief of the Defence Staff (Military Strategy & Operations) from 2018 to 2021, and is the current Master of Emmanuel College, Cambridge — joins Professor William Hurst to discuss the importance of having local and regional political understandings whilst carrying out military campaigns. They also explore how actors in war should understand their own positionalities, and reflect on how their own biases and relationships impact their knowledge and judgements.
