I Build a Modern Shelter in Fantasy World

They were the best soldiers Uncle Sam could offer. When their Black Hawk chopper crash-lands them in the middle of nowhere, Captain Gideon and his team realized that they were in a fantasy world. No Wi-Fi, no electricity, no backup, and no clue how magic works, these four elite soldiers do what they do best, improvise! Together, they transform a humble village into a modern shelter, forge alliances with mythical races, and defend the people from invading forces. When they say dragon, Gideon just say launch to SAM launcher. — Description from novelcodex.org
