Fourth Generation Warfare (4GW): Recommended Reading The Sling and The Stone: War in the 21st Century, by Colonel Thomas Hammes US Marine Corps, was published on 25 Nov 04. The Colonel is still on active duty and has spent most of his 29 years serving in Infantry and Intelligence assignments: his book explores the evolution and practice of 4GW, which has repeatedly succeeded against superior powers such as France, Russia and the US. Comment: ‘The Sling and The Stone’ (ISBN: 0-7603-2059-4 in hardback for £16:99) is highly recommended. Although aimed at the US Department of Defense, the book contains a great deal of thought-provoking material for those serving with other Armed Forces. ‘The Sling and The Stone’ is available through all good bookshops or it can be ordered direct from Grantham Book Services (Tel: 01476-541080).
