Future War In Cities [PDF ebook] 
Rethinking a Liberal Dilemma

This book is the first full-length study of a key security issue confronting the west in the twenty-first century, urban military operations — as currently being undertaken by US and UK forces in Iraq. It relates military operations in cities to the wider study of conflict and security in an era of urbanisation, expeditionary warfare and new power.
