On March 20, 2003, Coalition forces launched the invasion of Iraq on a massive scale. Their armored, fighting vehicles faced an uncertain level of resistance, and soon had to overcome a wide range of enemy threats. These included tank vs tank clashes during the first days of the invasion (most famously at Basra and Mahmoudiyah), and subsequently the dangers posed by enemy rocket-propelled grenades, cannon fire, antitank guided missiles, and improvised explosive devices. Dr Chris McNab covers both the opening clashes between opposing AVFs and the tactics developed by Iraqi insurgents seeking to neutralize Coalition superiority. Drawing upon first-hand accounts and official post-battle analyses, he examines how Coalition forces responded to the changing nature of the threats. Among the topics addressed are the coordination between Coalition infantry and air power; how dealing with roadside bombs in Iraq resulted in developments in equipment, tactics, and force structure; and the lessons learned for future warfare. The result is a fascinating study of how Coalition forces handled a unique multi-threat environment.
