Terrors of War, Suffering of Soldiers
Okay, so Wilfred Owen isn't the only poet to write about the experience of being a soldier. But he did it as powerfully as anyone. Plus, there aren't that many poets who actually were soldiers, and there are even fewer who wrote their war poems while in the midst of armed service. And because he died so young, with the war still going, his whole body of poetry is pretty focused on the struggle and futility of a soldier's life on the front. So if you see a war poem with stirring images, irregular meter, and the sharp tongue of a war-weary vet, then you're probably reading Owen.
