Are there any novels that combine elements of modern warfare and travel through ancient times, or novels where modern armies travel through ancient times?
I recommend the following two novels to you. I hope you will like them! 1. " Summoning Mercenaries " was a novel about the infinite universe. It told the story of the protagonist who traveled to different game worlds and summoned mercenary teams in modern warfare to solve various problems. Among them, there were already worlds of modern warfare games such as Resident Evil and Call of Duty: Modern Warfare. 2. One Piece: Field Marshal was a light novel that was derived from a doujinshi novel. It was about an army soldier who unfortunately died and traveled to One Piece's world. From then on, a world-famous army appeared in One Piece's world. The main character was the commander-in-chief of the army. He led the army with terrifying strength and carried the word 'justice', becoming the target of pursuit by all the major forces. This novel not only included the battles of the army, but also his application and development of modern military systems and concepts.
