Remains is based on real testimonies from British soldiers in Iraq, featured in 'The Not Dead' by Armitage. He exposes how war causes lasting psychological trauma, using the soldier’s internal conflict to show the emotional and moral cost of killing. Armitage critiques how modern warfare dehumanises and isolates soldiers, even after they return home. The speaker feels guilt, trauma, and detachment, haunted by vivid memories and a loss of identity. Through this, Armitage presents a raw, disillusioned view of war and its unseen, permanent consequences.
