He'd be more disciplined. His character would be shaped by military values. He'd be less likely to act impulsively and more likely to think things through strategically.
There's also 'Harry Potter and the Military Academy'. In this fic, Harry discovers a hidden military academy in the wizarding world and has to learn military tactics along with his magic. It gives a whole new perspective on his character development.
The world - building aspect. 'Harry Potter military fanfic' can expand on the wizarding world by introducing military institutions, ranks, and equipment. It can show how the wizarding society functions in a more regimented way compared to what we see in the original books, like how they train new recruits, how they allocate resources for war, and how different magical families contribute to the military efforts.
It could be really interesting. Maybe Harry would grow up with military discipline. He'd be more physically fit and have a strategic mind from an early age. His Hogwarts experience might be different as he'd approach challenges with military - like thinking, for example, in the Triwizard Tournament.
It could be about students learning combat magic instead of regular spells. For example, they might study defensive spells for battle situations like a powerful shield charm that can withstand dark magic attacks. They could also have military - style training in formations and strategy, much like real - world military academies but with a magical twist.
There are military Harry Potter fanfics that focus on the Aurors as a military - like force. In these stories, they could be trained in more military - style combat magic, with strict hierarchies and battle plans. Maybe they have to deal with a large - scale invasion from a group of dark wizards who are organized like an army.
He'd probably use his quick - thinking skills. Harry has been through a lot at Hogwarts, so he'd likely adapt well. He'd figure out the rules of the military camp quickly and follow them while still being himself.
In the fanfic, Harry Potter going to military camp would be really interesting. Firstly, his magical abilities would surely give him an edge in certain military drills. He could use spells to create illusions during stealth training. Also, his experience in fighting dark wizards would make him a valuable asset in strategic planning. He might face some challenges too, like having to hide his magic from others in the camp all the time.
In fanfic, the military aspect can make the wizarding world more organized and strategic. For instance, there might be a central command for magic - based military operations. This changes the way battles are fought compared to the original series. Instead of individual duels, there could be large - scale magical battles with troops of wizards and witches.
Harry would become more disciplined. His natural leadership skills would be enhanced by the military training, making him even more of a force to be reckoned with.
