In the Wake of the Tank - Gifford Le Q Martel - Bog

This very good and early tank book, written by a pioneering British military engineer and tank strategist who knew his subject firsthand. This is an excellent study written with an engineer's eye for mechanical detail. With good plates and chart of tank specifications and capabilities. Contains much on the experimental work of the 1920s. Martel served as a Brigade Major of Heavy Branch Machine Gun Corps, and at Tank Corps HQ in France in 1917-18 as a General Staff Officer, and his book is on the reading list of all serious students of armoured warfare.
