Survey Corps

The Survey Corps (also referred to as the Scout Regiment and Recon Corps) is a branch of the Paradis Island Military. Of the three military divisions, the Survey Corps is the most actively involved in direct Titan combat, Titan study, human expansion, and outside exploration.

History
The Survey Corps was founded by Bloodstone, approximately eight years after the walls were constructed. She was determined to continue fulfilling her duty as a Crystal Gem (to protect the Earth and all that lived on it). Bloodstone went to the king and asked for his permission to create a military division that specialized in exploring outside the walls, which he gave.

Bloodstone acted as the Survey Corps' first commander. All of the early expeditions ended in failure, usually with Bloodstone as the lone survivor. The government started to question the Survey Corps and Bloodstone's leadership. Desperate to see the Survey Corps succeed, she decided to step down from her role as commander, stating that she was more someone meant to follow rather than someone meant to lead. From this point on Bloodstone took a backseat and became more of a "behind-the-scenes" figure for the Survey Corps.
