After an accident, our main character woke up with the memories of another life alongside his own. The memories, experiences, and emotional issues of a middle-aged war veteran and family man from Earth find a home in the head of a simple farm boy in a LitRPG driven world. Our main character is imperfect in an imperfect world, he can make mistakes, come to the wrong conclusion, fail, and he has enough experience know it. His experiences make him overpowered for is age and otherworld knowledge give him an unbreakable edge, but what is individual power against a world that has armies of battle-hardened soldiers, legions of adventurers who are hundreds of years ahead of him? Instead one man will try do the right thing, the American thing. He will do what a lifetime of experience taught him to do, the bare minimum until he has a chance to quit.

I like to think of this story as an Isekai with some hair on its chest.
