The 20th century heralded a revolution in how wars are fought. From military strategy and planning to the weapons and equipment used on the ground, modern militaries have radically changed how they operate. So what major changes have there been? And what is the purpose of war in the first place?

Dan is joined today by Mike Martin, a conflict scholar who specialises in modern warfare, to discuss its evolution and development over the past century.

Produced by James Hickmann and edited by Tomos Delargy.
