3rd Battalion - K Company
30th Infantry Division
Order of Battle for 30th Infantry Division
The "Order of Battle" or "ORBAT" for the U.S. Army participating in the European Theater of Operation in World War II showed the hierarchical organization, command structure, strength, disposition of personnel, and equipment of units and formations within the 30th Infantry Division. During the war, this information was kept highly secret. As combat operations develop during a campaign, orders of battle were revised and altered in response to the military needs and challenges. The Order of Battle changed depending on requirements as the battle as it was being fought and as units were reassigned or replaced. The Commanding Officers reflected these changes in their "after action" reports (dispatches).
After the war, the 30th Infantry Division's "Order of Battle" during the different phases of the war became a part of the units history and were no longer considered classified information. The following table shows a simplified version of the Order of Battle for the 30th Infantry Division.
