Instead, it was a 47-page meditation on retreat, deception, and the tactical utility of moving backward while facing forward.
There are three theories.
Conventional wisdom: momentum favors the attacker. Reverse art: controlled backward movement forces the enemy to advance into your killing zone. A tank reversing at 8 mph along a prepared route can fire more accurately than an enemy advancing at 25 mph over unknown ground. The manual included rare data from captured German gunners, who admitted that advancing against a retreating but shooting enemy induced vertigo and rushed shots. classified the reverse art of tank warfare
The manual prescribed a brutal training regimen. Crews practiced “reverse gunnery” on courses where targets appeared behind them. Drivers learned to steer by mirrored periscopes alone. Gunners calibrated their lead for targets that were closing faster than their own retreat. Commanders drilled a single phrase until it became reflex: “We are not fleeing. We are aiming.” Inside was a document that would later be
To master reverse art, a tank commander had to unlearn ten thousand hours of instinct. Conventional wisdom: momentum favors the attacker
Why was such a potentially valuable doctrine classified and then buried?
