I recommend the novel "Special Forces from the Edge." The female protagonist transmigrated to the world of "I am a Special Forces" and became a soldier of the Iron Fist Regiment. She obtained the Special Forces Engine System and gradually became the King of Soldiers, the strongest special forces soldier among the special forces. The male lead was a general who had transmigrated to this world and became a special forces soldier. The two of them met because of their work. As time passed, the relationship between the two slowly warmed up. I hope you like this fairy's recommendation. Muah ~😗
