Where did service personnel live while on duty and who were their commanders in World War 2?

During World War II, service personnel typically lived in military barracks, tents, or other temporary accommodations near their bases or front lines, depending on their assignment and the conditions of the war. Commanders varied by country and unit but included high-ranking officials such as General Dwight D. Eisenhower for the Allied forces and Field Marshal Erwin Rommel for the Axis powers. The command structure was hierarchical, with orders flowing from senior leaders down to lower-ranking officers in charge of specific units.
