442 Infantry Regiment Question

My father was a member of the 473rd Infantry (converted from Antiaircraft). This came from Wiki. A great deal of information about the 92nd is being re-evaluated.
After continuing poor combat performance including many instances of unauthorized withdrawals upon meeting the enemy, low morale and malingering, the 92nd Infantry Division was considered of inferior quality both by German and U.S. commands and fit for only defensive roles. Things deteriorated to the point that the division was withdrawn from the lines and rebuilt in early 1945 with the removal of the 366th Infantry Regiment (formed into two engineer general service regiments) and the addition of the 473rd and 442nd Infantry Regiments. Many historians have begun to reevaluate the combat record of the 92nd Division as contemporaneous reports of its honorable performance have continued to surface. Numerous veterans of the division believed that the reports of poor performance were motivated by racist sentiments present within the senior officer ranks. Even as evidence mounts in support of the division's honorable conduct, some still seek to suppress these facts.[14] The famous and highly decorated Nisei 442nd, made up of Japanese Americans, was withdrawn from the fighting in France to bolster the division's combat effectiveness.
