A camouflaged M4 Sherman tank fitted with a T34 60-tube 4.5-inch Rocket Launcher (Calliope) from the 17th Armored Group attached to the 76th Infantry Division, LT Gen. George S. Patton’s Third Army, carefully crosses over a Treadway bridge circa early March 1945 near Biesdorf in the Rhineland-Palatinate region of Germany.

More on the Calliope via Mark Felton: 

Activated at Fort Knox, Kentucky on 20 March 1943 as the 1st Armored Group then redesignated as 17th on 20 November 1944– three months after they landed in France– the 17th AG was attached to MG Manton S. Eddy’s XII Corps headquarters and served as a tank fire brigade. The unit crossed into Luxembourg on 21 December 1944 during the Ardennes offensive and entered Germany on 3 March 1945, helped capture Frankfurt (and the stash of art treasures and gold in a salt mine at Merkers) then finished the war in Austria, linked up with Red Army units.

Following post-war occupation duties, they inactivated in Belgium on 30 April 1946.
