I Was Summoned as the Weakest Hero, But I Awakened a Military System

John Smith was a nineteen year old American man who found himself transported to another world along with a whole class of Japanese senior high students. They were surrounded by priests who told them they are heroes and must defeat the Demon Lord Forces for the sake of world peace. Everyone was above B-rank, which is considered already the strongest in the worlds’ standards. But for John Smith, he was not in those categories, instead he was the lowest of the low. E-rank. When they learned about it, he was marked as useless and threw him into a dungeon to die. However, what they didn’t know was that despite his weak stats, he awakened a system called “Military System” where he could summon guns, soldiers, military vehicles, aircrafts, ships, and other kinds of military hardware. It doesn’t matter what kind of monsters he’ll encounter inside the dungeon, he’ll just shoot them all, machine guns, rocket launcher, everything at his disposal. And he swore to himself that once he got out of the dungeon, he’d take his revenge.. It doesn’t matter how powerful they are, they won’t be able to survive the relentless bombing from an AC-130, or can dodge an AIM-9 Sidewinder missile. He’ll do it in an American way. — Description from novelcodex.org
