Where did lieutenants sleep in World War 1?

During World War I, lieutenants typically slept in command tents or makeshift quarters near the front lines, depending on the situation. In more stable areas, they might have access to dugouts or more organized barracks, while in active combat zones, they often had to make do with whatever shelter was available. Conditions were often cramped and uncomfortable, reflecting the harsh realities of trench warfare. Privacy was limited, and sleep was frequently interrupted by the sounds of battle.
