Answerand Explanation:
The title can be seen as ambiguous because the author shows how soldiers, in a war, are exposed to everything and at the same time to nothing.
This is because the author presents the idea of intense monotony to which soldiers are subjected during the course of a war, where their lives fall into a discouraging, boring and extremely stopped routine. In this monotony, soldiers are exposed to nothing. However, the author also addresses how soldiers are exposed to all kinds of adverse factors, since they live in terrible conditions of hygiene, food, housing, climates and any other factor that affects health and well-being.
In this poem, Owen is exposing the life of the soldiers in the middle of the war, showing that there is nothing inspiring and worthy of admiration.
