Ok, so you have a two nations going at it in interplanetary, interstar system worlds. The nation we would be playing has attack this world along with a few others in an ongoing push towards the eradication of this other nation. This is predominantly a racial sort of war, perhaps even based on creed. This all stems from a series of wars dating back nearly two centuries by now(somebody attacks this one, pushes that nation toward the brink sets up terms of surrender that sets a peace for a few decades before the other attacks again; rinse and repeat). 

Anyway, this particular operation on this planet is reaching a standstill. The enemy is becoming more partisan, more guerrilla, and far more diehard. They've started pushing back, even through all the orbital bombardment and all the large scale land war, the hold on. The attrition is starting to make the Operation not worth the effort, and the death toll is rising. 

A pincer movement has shut off a a couple of battalions in a large city, and enemy troops are so close orbital measure would do more harm than good for our troops. And thats where our story starts. Again, I am open for ideas or suggestions , and all support is greatly appreciated!
