User blog:The Triad/Missions in MGSV

I have seen the achievements and trophies for Metal Gear Solid V: The Phantom Pain which are concerning missions which are below:

Completed "PROLOGUE: AWAKENING" mission.

Completed "PHANTOM LIMBS" mission.

Completed "WHERE DO THE BEES SLEEP?" mission.

Completed "HELLBOUND" mission.

Completed "TRAITORS' CARAVAN" mission.

Completed "VOICES" mission.

Completed "METALLIC ARCHAEA" mission.

Completed "SAHELANTHROPUS" mission.

Completed "A QUIET EXIT" mission.

Completed "TRUTH: THE MAN WHO SOLD THE WORLD" mission.

I know there are a lot of missions in the game including side missions but these are not the only main missions are they?
