This is what Pics look like when I acutallly take my time on them lol.
I felt the need to make a sad pic : (, so we have a major here who has lost his wife to sickness. The only one he's had for almost all his life and just cant seem to let her go, so, in an attempt to reunite with her, he reviews a photo of her, its too much to take.....he ends up pulling the trigger.

I think this song sounds amazing with this piece > http://www.youtube.com/watch?v=Z8mdKRlOdeo

Sangheili/elites belong to Bungie
Edit:
For everyone wondering about the human structure and weapon {M6C} this is after the events of halo 3 and on a human/sangheili first colonized planet, being more of a human planet, making there alliance stronger, he just got back from his military duties from a base he was stationed at, he got to thinking, and this happened. Plus were he shot himself was in throat through his neck, he placed the pistol in his mandibles.
