Colonel John Musgrave served for 35 years in the Royal Regiment of Artillery. He has led the development of the British Army’s joint fires capability, has run firepower in a NATO corps headquarters and commanded the Royal School of Artillery. His book Firepower: Making 21st Century Warfare Decisive reflects his experience in these roles, and his personal experience as a serving officer, of the West’s failure to achieve lasting peace in a series of post-Cold War conflicts. He is a regular speaker at international level on Artillery and Firepower theory and practice, and currently leads a major change programme within the British Army.
