It would be a big change from campaigns to take planets, asteroids, ships involving large land and space battles and the surrounding political climate of the war and how it all effects this squad of Marines to writing that kind of thing.

I know how you feel. My normal writing was political commentary on my time and engineering issues at work. The switch to relationship short stories was always a shock.
