The Military Police Brigade (憲兵団 Kenpeidan) is the most prestigious military sector due to their work, which allows citizens to live safely within the inner Wall and access to abundant resources. Therefore, it has higher authority over other military sectors. However, in reality, it is the most corrupted military sector due to a lack of oversight compared to the other sectors of the military. Due to their misuse and abuse of power, the Military Police Brigade is also at odds with the Garrison and especially with the Survey Corps. Only the top ten alumni from trainee squads can apply for the Military Police Brigade. However, there are other ways to get in the sector such as fraternization, favoritism, etc.

Duty:
The Military Police Brigade is the primary police force within human territory. Not only do they maintain order, they serve as the king's guard. Since they do not normally come in contact with Titans, they must have special permission to use vertical maneuvering equipment and usually carry firearms instead. They are also in charge of tax collection and land distribution. They frequently abuse these duties to exploit resources and food from civilians. Primary duties also include supervising of the Training Corps, monitoring the Garrison, and directing fire-fighting operations. They are also responsible for the arrest and detainment of political criminals and major offenders. The Military Police Brigade is given the priority during investigations that involve nobility or the royal family.

Structure:
The Military Police Brigade is an organization with 2,000 members, with direct command over 3,000 additional personnel from the Garrison. This brings their total potential manpower to 5,000 soldiers. About 200 MPs are stationed in each walled city.

Qualities:
The Military Police Brigade is intended to be an elite unit made of the most skilled soldiers due to its rigorous standards. However, the reality is a lazy and corrupt system that selfishly benefits from the powers granted to it, with these powers being constantly abused and taken unnecessarily advantage of. Though they are from the top ten graduates from the trainee squads, they are inexperienced as they only stay in the safety of Wall Sheena and do not directly engage in battle with Titans. Senior officers have been seen spending all their time gambling and drinking while leaving recruits to do all the work. They also pilfer taxes and misappropriate land. This corruption is well-known with many people (even to Wall Sheena citizens) criticizing their lack of care for anyone other than themselves. Refugees and forced laborers (called producers) hold simmering hostility against them. However, many trainees still dream of joining the Military Police Brigade, because it will allow them to live within Wall Sheena in safety. Also, being so close to the center of human territory, most policemen have relatively little experience fighting Titans as compared to the Survey Corps or the Garrison. This, together with corruption, loose discipline, contempt from public, abuse of power makes this military branch the most incompetent out of the three.
