A press event has been going on this week at Konami's LA offices for Metal Gear Solid V: The Phantom Pain. As tends to happen, some bits of information have made their way online from this event despite there being a full embargo until June 9.

One of those pieces of information are the names of the missions from just the first chapter of the game. I'll toss them in spoiler tags for those who don't want to have anything about this game spoiled for them.
Awakening
Revenge
1 - Phantom Limbs
2 - Diamond Dogs
3 - A Hero's Way
4 - C2W
5 - Over The Fence
6 - Where Do The Bees Sleep
7 - Red Brass
8 - Occupation Force
9 - Back Up,Back Down
10 - Angel With A Broken Wing
11 - Cloaked in Silence

At present, the names of the chapters themselves are not known. These originally came from a posting on A9VG.
