Who is Mr. Dollimore from The Wanting Seed and what is their importance?

Mr. Dollimore is the lieutenant in charge of the army battalion to which Tristram is assigned. Dollimore is a fool whose concept of war is drawn from poetry and scenes from old films to which he was exposed during officer training school. He believes the government's war rhetoric implicitly, never for a moment doubting that the cause is glorious, and even threatening to shoot Tristram as a traitor when he asks questions. Dollimore rushes over the parapet in battle, and is immediately killed.
