Pick a soldier (can be anybody from this website): http://apps.washingtonpost.com/national/fallen/

It involves getting to know whoever you’ve picked who has, currently is, or will be serving in the military (if possible one who is, has, or will be deployed in a combat zone).
They can also be one who has been wounded or has died.

Find out as much information as you can about that soldier (can be on other websites too once you’ve picked who you want to write about), for example: their home town, branch of service, age, where they were deployed, their job in the military, rank, etc.

Also look for information that tell you something more about them as a person, their family, why they joined, what they think about serving in a time of war, what others think about them, etc.
