During the battle for the bridge at Remagen, German forces mobilized "Sturmmörserkompanie" 1000 and 1001 (a total of 7 units) to take part in the battle. The "Sturmtiger" were originally tasked with using their howitzers against the bridge itself, though it was discovered that they lacked the accuracy needed to hit the bridge. During this action, one of the Sturmtigers in "Sturmmörserkompanie" 1001 near Düren and Euskirchen allegedly hit a group of stationary Shermans tanks in a village with a 380mm round, resulting in nearly all the Shermans being put out of action, and their crews killed or wounded. This is the only tank-on-tank combat a Sturmtiger is ever recorded engaging in. After the bridge fell to the Allies, "Sturmmörserkompanie" 1000 and 1001 were tasked with bombardment of Allied forces to cover the German retreat, as opposed to the bunker busting for which they were originally designed.
