What may have made the soldiers feel so detached?

Soldiers may have felt detached due to the psychological toll of combat, which can lead to emotional numbness as a coping mechanism against the trauma of war. The intensity of their experiences, combined with the need to suppress emotions in order to perform their duties, can create a barrier between them and their feelings. Additionally, the harsh realities of military life and the constant exposure to violence can foster a sense of alienation from both their humanity and the civilian world. This detachment can serve as a protective strategy but often results in long-term emotional challenges.
