The Fallen Warrior - A Character idea

So I have just watch an add while watching a video online. It was for PragerU. An add for memorial day here in the US. It told a story of a soldier throughout the major conflicts we had. And it was really amazing the acting in it. But it got me thinking. An American soldier, one that reincarnated every time he died. He would reincarnate and fight for his country in the next war, taking what he learned from the last one in the next one. But finally he dies and reincarnates in Equestria. As...well. That's for the writer to decide. But he would serve to fight for Equestria on ward. It would be a nice story to write. Especially for this coming up American holiday. A one shot of sorts.
