After a Car Accident, I Joined a Mysterious Unit and Fought Across the Country

Modern Urban Story, Guns, Ruthless Killing. I Really Can’t Find Any More

I want books similar to Los Angeles Tough Cop: I Master Every Form of American-Style Quick-Draw Combat (American Tough Cop).

Special Forces Stories, But Not Too Over-the-Top

Any Modern Military Stories Where the Protagonist Rises Step by Step, Without a System?

I want to read books like "Enlisting as an Inspector: Do I Need to Leave the Army Early?"

Looking for Spy or Assassin Stories That Are Grounded, Logical, and Have a Clear Main Plot

Looking for books similar to "Spy War: I Can Actually Identify Spies". Don't make the male lead a loser who flirts with every woman he meets and can't bring himself to hurt any of them. Don't have him acting like some big shot from the start. I want an ordinary man who works hard to survive and helps his country when he has the ability to do so.
