Halo fan story

Alright, so I’m kinda stalled on my first and current fanfic about my own Spartan-III Headhunter, and now my mind is stuck on a different character/story/location I can do. I want to do this one on an ODST or Marine, and I want it to take place during the Battle of Reach from the game.

I have a scene in my head where this character and their squad are in a couple Warthogs during the intro to Tip of the Spear when the two armies collide. But for the life of me, I can’t think of a bigger plot and mission for them afterwards. It’ll probably go in the direction of them going to another cloaking spire, separate from the one Noble 6 went to, and pushing up there, but I don’t want it to end at that point.

Any suggestions?
