I Became a Genius Commander at the Academy

A military enthusiast with dreams of serving, shaped by his father's influence and a bookshelf full of war theories, finds himself unexpectedly reborn into a fantasy world he'd recently read about.

Now an orphan, he faces impending destitution in a land governed by strict caste systems. But with the Reich Empire Academy Entrance Exam as his potential salvation, he's armed not with magic, but with a vast knowledge of military tactics from his past life. As the date of his expulsion from the orphanage looms, he's determined to leverage his unique skills to change his fate.
