The US Army’s sole encounter with the Tiger I in France occurred on August 28, 1944 when the 486th AAA Automatic Weapons Battalion of the 3rd Armored Division intercepted a train with three battle-damaged Tiger I tanks being sent back to Germany for rebuilding. The M15A1 antiaircraft halftracks swept the train with 37mm automatic cannon and .50-caliber machine-gun fire, preventing the German crews from manning the tanks. As can be seen from this view, the Tiger I tanks were fitted with the narrow transport track since the normal track was too wide for use on railroad flat-cars.
