Soon after the move to Camp Pickett, on 22 October 1943, the unit was redesignated as the 746th Tank Battalion and adopted the organization in which it would fight throughout the European Campaign.

It then moved in March 1944 to Castlemartin Range, Pembrokeshire, South Wales, where it conducted live fire and maneuver training at the company level and below.

Company D, along with the reconnaissance and mortar platoons and selected support elements landed ashore in the early morning hours of 7 June.

On 5 July, the 746th Tank Battalion was attached to the 83rd Infantry Division to help repel a strong counterattack from the German 6th Parachute Regiment[15] toward Carentan in an effort to cut off the VII Corps from their supply lines to the landing beaches.

Although remaining attached to the medium tank companies, they were used to maintain security along the lines of communication, where bypassed and infiltrating German troops continued to pose a real threat; to protect the infantry regimental and battalion command posts; and as a tactical reserve.

They had advanced to the vicinity of the Lozon River west of St.-Lô by 25 July, when the Allied carpet bombing of German positions south of the St.-Lô-Périers road marked the beginning of Operation Cobra.

During the next several days the tankers encountered stiff but increasingly disorganized and isolated resistance and advanced to the environs west of Marigny by 29 July.

[3] The 746th Tank Battalion went back into action on 1 August east of Villedieu-les-Poêles to help exploit the breakthrough in the German defenses.

Initially the 9th Infantry Division made good progress, covering 10 miles in two days (an advance unheard of in the bocage),[16] but German efforts to restore stability to their front caused resistance to stiffen.

Beginning on 4 August, the medium tank companies maneuvered with their infantry regimental combat teams in an effort to dislodge the Germans located between Chérencé-le-Roussel and Gathemo.

Then turning northeast, the battalion advanced about 30 km per day, encountering continued sporadic resistance in the form of mined roadblocks, demolished bridges and mobile strong points.

[19] As they crossed into Germany, the 746th encountered its first organized resistance since breaking out of Normandy when they began to probe the Western Wall (Siegfried Line).

[4] Breaking through the first band of the Western Wall by late September 1944, the 9th Infantry Division, and along with it the 746th Tank Battalion, were the first of numerous American units to find themselves in the dark, disorienting woods and hilly terrain of the Hürtgen Forest.

[4][22] In particular, companies B and C saw heavy action in the Forest until the battalion withdrew from the line on 28 October to Bütgenbach, Belgium, near the village of Weywertz.

Company A remained in support of the 47 Infantry Regiment, which had been attached to the 3rd Armored Division in order to sustain its defense of the gains made at Schevenhütte.

However, due to the German counteroffensive in the Ardennes just to the south that began the day before, the scope of the attack was reduced while the division reacted to this new threat.

[25] Company A joined the 47th Infantry Regiment when it was detached from the division and attached directly to V Corps to reinforce the northern shoulder of the American lines.

[25] The battalion remained in defensive positions to the southeast of Eupen throughout the end of December 1944 and most of January 1945, with limited localized offensive operations while the front to the 9th Infantry Division's south was stabilized and restored after the German counteroffensive.

[27] The discharge gates on the dam were demolished as the Americans approached and operations to the east of the Roer had to wait until the waters downstream subsided.

German positions continued to offer excellent visibility for artillery fires, and assault guns and dug-in infantry created dangerous strong points that had to be reduced one at the time.

Companies A and B, crossed the Rhine with their infantry regiments on the bridge at Remagen on 8 March, and immediately went into action to defend and expand the bridgehead on the east bank of the river.

[29] The 9th Infantry Division as well as other units pressed across the Rhine into the bridgehead gradually expanded their perimeter until German resistance collapsed on 25 March.

With infantry mounted aboard the tanks or following in trucks, the 746th tankers moved about 110 km east to positions in Marburg to north of Giessen by 30 March.

At this point, the 9th Infantry Division was pulled from this headlong eastward advance and attached to III Corps to move north to prevent an expected German breakout from the eastern perimeter of the Ruhr pocket in the vicinity of Winterburg.

[29][30] By mid-April, the 9th Infantry Division was effectively squeezed out of the shrinking cordon around the Ruhr Pocket and plans were made to pull the 746th out of the line to refit the worn tanks.

[32][33] The routine of occupation was briefly interrupted on 16 June, when ordnance in the old Bavarian fort was inadvertently set off in their bivouac area, resulting in an explosion and fire that lasted two days, but which fortunately caused no casualties.
