By the war's end, infantry division commanders "unanimously agreed that they would prefer to have the support of a tank battalion instead of a tank destroyer battalion." The result was a belief that each infantry division would have its own dedicated battalion of three tank companies, with each company serving each of the three Infantry Regiments. This made the Tank destroyer doctrine obsolete, since tanks themselves could also serve in the role of a mobile anti-tank defense against any potential enemy armored thrust, a tactic that had been proven during the Ardennes.
