Introduction: When a fantasy kingdom needs heroes, they skip the high schoolers and summon hardened Delta Force operators.Lieutenant Cole Mercer and his team are no strangers to sacrifice. After all, what are four men compared to millions of lives saved from a nuclear disaster? But as they make their last stand against insurgents, they鈥檙e unexpectedly pulled into another world鈥攐ne on the brink of a demonic incursion.Thrust into Tenria's realm of magic and steam engines, Cole discovers a power beyond anything he'd imagined: magic鈥攁 way to finally win without sacrifice, a power fantasy made real by ancient mana and perfected by modern science.But his new world might not be so different from the old one, and the stakes remain the same: there are people who depend on him more than ever; people he might not be able to save. Cole and his team are but men, facing unimaginable odds. Even so, they may yet prove history's truth: that, at their core, the greatest heroes are always just human.                                                                                                                                                                                                Character Growth                                                                                    Clever Protagonist                                                                                    European Ambience                                                                                    Fantasy World                                                                                    High Fantasy                                                                                    Isekai                                                                                    Magic Formations                                                                                    Magical Technology                                                                                    Male Protagonist                                                                                    Military                                                                                    Modern Knowledge                                                                                    Monsters                                                                                    Multiple Transported Individuals                                                                                    Portal Fantasy                                                                                    Soldiers                                                                                    Steampunk                                                                                    Strategist                                                                                    Sword And Magic                                                                                    Teamwork                                                                                    Transported to Another World                                                                                    Wars...
