Military

Humanity's defense against the Titans is a full-time, professional army trained to deal with the beasts. The military (軍事) is divided into three divisions: the Survey Corps, which explores outside human territory to hostile areas in a bid for expansion; the Garrison, which patrols and maintains the Walls, keeping Titans out and acting as the first to engage the Titans if the gate is destroyed; and the Military Police Brigade, the top-ranking soldiers who serve as the personal guards for the king and maintain order within the Walls. After the truth of about the Titans is revealed to the public, the Military changes their focus to fighting Marley.

Structure
The military is divided into three divisions, each led by their own leaders, but all subordinate to Darius Zackly, the Commander-in-Chief of all three.

The Survey Corps
Ranked among the most elite soldiers, they are tasked with attempting to reclaim territory that has been lost to the Titans. Despite being the most well trained, they often come under dispute from those within the Walls and are constantly under threat of being disbanded since they suffer high losses, and usually fail to supply results. The current commander is Hange Zoë.

The Garrison
The Garrison is responsible for patrolling and protecting the Walls. They are set the task of evacuating citizens and dispatching Titans in the case of an emergency breach in the Walls. The current commander is Dot Pixis.

The Military Police
The Military Police are in charge of keeping order inside the Walls and protecting the ruling monarch, currently Historia Reiss. Due to their important function as guardians of the most important humans, only the top 10 trainees from a graduating class are permitted to join them. Despite recruiting from only the best, they are shown to be corrupt and often incompetent due to the nature of their work inside the Walls, far away from Titans. The current commander is Nile Dok.

Qualities
Though the army is full time and has protected the Walls for over 100 years, it is largely corrupt. The Military Police are thought to be the worst, as they actively avoid fighting the Titans, preferably staying alive in the interior. They are also responsible for the lack of technological advancement as well as numerous, other issues inside the Walls. Under them is the Garrison, viewed to be lazy, irresponsible, and cowardly. After the breach in the Shiganshina District,  though,  their tactics and personnel have achieved amazing improvements. The Survey Corps are the least corrupt of the three, fighting only for the sake of humanity and reclaiming the land lost to the Titans.

Uniform & Equipment
All members of the military, excluding the Training Corps instructors, wear similar uniforms consisting of a short, light brown jacket with the badge of the squad on both shoulders, on the front left pocket and on the center of the back, a light-colored shirt, a dark brown sash around the waist covering the hips, white pants, and dark brown knee-high leather boots. The Training Corps instructor uniforms differ slightly from the other branches, including an olive-green trench coat replacing the jacket of the other factions. The Survey Corps members often wear a heavy, green, hip-length hooded cloak with the Wings of Freedom on the back, usually when conducting missions outside of human territory. Trainees have been observed to wear the cloaks, albeit without any symbols when conducting marches in the rain. When on official business within the walls soldiers wear a long coat with their branch insignia. In preparation for the Battle of Liberio, the military created a predominately black uniform for the Survey Corps to wear for night infiltration into Marley.

The main equipment of the military is the vertical maneuvering equipment, which is also their main weapon used in conjunction with two snap-off blades attached to the hand grips. However, the Military Police often use muskets, since they mostly deal with people and rarely with Titans.

Trivia
