In the poem Disabled, what does the author say about the effect of war?

Owen does not shy away from depicting the horrors of war. He makes his reader confront the atrocities on the battlefield and the indignities of life back home. He presents readers with soldiers who have lost their limbs and been victims of poison gas; young men mourning their dead comrades; ghastly battlefield dreamscapes; a cacophony of sounds terrifying in their unceasing monotony; and Nature's wrath. He shows how the war affects the young men who fight both physically and psychologically. The men who survive become inured to brutality. There is little to no glory and heroism, just scared or desensitized young men fighting for a cause they do not quite understand.
