Being completely honest as this is a competition, this feels incomplete. I understand the story, but I feel there was no plan. It was just a fight with an unexpected enemy. There was no planning step and the hole battle was chaotic and impulsive, which is good for a battle, but bad for a plan. Also next time feel free to be more descriptive. How did the battle field sound? Did the guns kick like a mule or was he able to keep control? Next time feel free to give the MC a few traits of their own. It felt a little like generic solder fighting a battle, which is fine but hard to make a connection to. I was able to understand the flow of the story but being honest nothing stood out or grabbed me. Please don't take this personal and continue to write and improve.
