The military (軍事 Gunji) of Paradis is a full-time professional armed force trained to deal with the Titans within and beyond the Walls. It 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 about the Titans is revealed to the public, the military changes their focus to defending Paradis from aggression from Marley and other nations.

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

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, their tactics and personnel have achieved amazing improvements. The Survey Corps is the least corrupt of the three, fighting only for the sake of humanity and reclaiming the land lost to the Titans.

Uniform and 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 and other firearms since they mostly deal with people and rarely with Titans. Later variants of the vertical maneuvering gear use pistols, bolt action rifles, and Thunder Spears to deal with enemy infantry, fortifications, and Titans simultaneously.
