One interesting Seal Team fan fiction could be about a mission that goes off - script. For example, the team has to deal with unexpected weather conditions during a rescue operation in a remote area. They have to use their survival skills in a new way to get the job done.
You should also do some research on military tactics and equipment, even if it's just basic knowledge. This will make your fan fiction more realistic. For example, learn about different types of firearms or communication devices used by the military. Start writing with a strong opening that grabs the reader's attention, like a high - stakes mission starting right away.
Another good one is 'Red Platoon' by Clinton Romesha. It's a fictionalized version of a heroic battle, and it does a great job of showing the courage and teamwork of the SEALs.
To some extent. Seal Team takes elements from actual operations and incorporates them into the storyline, but it also adds fictional elements for dramatic effect.
