What is the song One by Metallica about?

Don't know why you need to know this but

Explanation: This song is about a soldier fighting in a war and a mortar blows off in his face. He can't hear, see, smell, taste and he doesn't have arms or legs. He comes out of a coma in a hospital. During the time he is in the hospital he reflects on his life and things his father told him. Eventually the doctors get worried because he's having spasms all the time, but he doesn't seem to be dying. They call in the general and he can't figure it out either but the soldier with the general recognizes it. "It's Morse code," he says. The general asks what he is saying and the soldier looks for a minute and then says, "He is saying K-I-L-L- M-E over and over again."

short

The song is about the idea of a soldier losing all of his limbs and being unable to hear, speak,or see, set to a world war I backdrop.
