Do you think you're hard? Do you think you're some sort of Tier Zero Modern Warfare Elite Ops Deniable Badass? Do you even think you know about such people? Until you've read this book, you don't know shit.

Cu Chi was a district just 25 miles from Saigon. Starting from the French Indochina War, local guerrillas carved tunnels out of the strong laterite clay that made up the district. By 1968, the Iron Triangle had over 200 miles of tunnels, with three and four level base camps including barracks, hospitals, and weapons shops. This book covers the Vietnamese men and women who lived and fought in the tunnels, and the American soldiers tasked with going in and smoking them out, the stone crazy tunnel rats.

The authors have compiled an extensive body of interviews with veterans on both sides of the conflict, bring forth the survivors own words as they describe living without sunlight or fresh air for months on end, and the terror of chasing the enemy into the bowels of the Earth. A secondary topic is weapons, from madcap high-tech schemes to destroy the tunnels, to the trained wasps and snakes that the VC used to defend their bases. Both the human and military elements are well-represented.

In the end, America never learned how to fight in the tunnels. Instead, in the wake of the Tet offensive, the army simply obliterated the entire district, first with defoliants, then with Rome plows, then with B-52 strikes that blew 10m craters in the ground. The guerrillas were essentially destroyed, but only at the cost of the entire region. The Tunnels of Cu Chi is a fascinating micro-history that amply demonstrates the fractally fucked up nature of the war.
