Do tanks trump technology? Do missiles matter more than manpower? And can the better thinker beat the stronger fighter?

Dr Mike Martin’s new book ‘How To Fight A War’ argues that psychology is the key, and that war is as at least as much a conversation as it is a physical battle.

The head of the Army, General Sir Patrick Sanders, has called the book ‘essential reading’.

Dr Martin explains his key principles which could decide victory, or defeat, and former soldier James Wharton gives us his thoughts on whether it all stacks up, based on his experiences of fighting in Iraq.
