Commander..? [REMAKE]

You're a Staff Sergeant in the military because your parents didn't want to send you to college (meanies). You were serving your 3rd tour of Afghanistan and one day you found a green crystal in a suitcase in an HVT building. What will that be though?

[Loosely based on Creeper_Corporation's story]

Extra notes here: This is a remake of my previous story of the same name. I've modified some parts of the story (totally minor), so this might be somewhat new to older readers.
