Book Review published on: December 23, 2025
H. John Poole’s book The Debilitating Tools of War is a history review of training and systems that were less than ideal for their purpose or failed to protect U.S. soldiers. The author does a particularly good job of explaining several issues with training and materiel using examples of Indian Wars, World War I, etc., but does not suggest how processes have changed over the last thirty years to improve on many of the issues he raises. Additionally, the changes in the operating environment, from counterinsurgency to large-scale combat operations, and no near-peer to two near-peer threats in just twenty years are barely considered. Someone reading the book could think the old ways of training, capability development, and materiel acquisition that produced the areas discusses are still in place. Poole does a very good job of explaining the “enemy” view of many positions and his research and experiences from his biography give creditability to his statements.
The book reads like a disgruntled employee’s exit interview. Without any citations, Poole makes several assertions about how the military, industry, and government don’t care about American lives. He hangs his hat on the 2015 report Lying to Ourselves: Dishonesty in the Army Profession by Leonard Wong and Stephen Gerras. While the report is valid, it focuses on tactical unit requirements and is out of context to the materiel and training requirement development criticized in the book. Additionally, many changes have been made over the last nine years in the U.S. Army to address those issues in the report. He uses a few examples from the 2000 Land Warrior project as a waste of money and effort but omits that research and development. While this may not lead to the original idea, it can often lead to other acceptable ideas. He references U.S. Marine Corps Fleet Marine Force Manual 1, Warfighting, as a source for how the U.S. military sees personnel in combat but that was replaced in 1997 by Marine Corps Doctrinal Publication 1, Warfighting, with the most current edition published in 2018. Sadly, these detract from a good thesis with good intentions, critical thinking points, and worthwhile recommendations.
He does make a good argument throughout the book about how the U.S. military has a superiority complex of soldier and materiel and not much of a focus on weaknesses and broken trust and lack of tactical training. When he discusses training and materiel, he emphasizes often that while the latest items may be good at helping detect/target the enemy, there is a gap in the capability to protect the U.S. service member.
For a book published in 2024, the author missed many opportunities to address his thoughts based on the ubiquity of drones and electronic warfare as observed in Ukraine/Russia in his drive to demonstrate the need to increase survivability. He does mention drones but uses a 2000 Israeli/Hezbollah example. He discusses the need for the U.S. military to train more for night operations but uses many Vietnam examples. He does not address how to conduct this training under constant aerial surveillance of infrared-capable drones. He gives very few examples from recent Iraq/Afghanistan conflicts and the Ukraine/Russian war that are changing much of how warfare is conducted and how the United States and its allies see future capability needs. More focus on relating World War II/Vietnam examples to recent operations would have been helpful to his argument.
He has chapters on different types of equipment from GPS, sensors, targeting, illumination, night vision, and thermal imaging. Most of these are filled with how the equipment did not work well in previous conflicts and how the enemy remained undetected by taking advantage of how the equipment operated.
His perspectives on Asian warfare and historical examples do raise important questions on how the United States would fight and if its doctrine would work in the worst-case scenario of a land war in Asia. He focuses on how small unit maneuver warfare remains constant and recommends changes to how small unit training should improve for future warfare.
I would not recommend the book to anyone other than those with a current informed
understanding of how the U.S. Marine Corps, U.S. Army, and Department of Defense conducts capability development, materiel acquisition, and training development as they can parse out the very informative parts from the less helpful portions. The book is very much rooted in the past. While informative, it would be more relevant to conduct the analysis using current or future operational environments.
