Anti-personnel vertical maneuvering equipment

Anti-Personnel Three Dimension Maneuver Gear was created by the Military Police specifically to combat the Survey Corps. The gear itself is an adaptation of the traditional 3D Maneuver Gear, allowing the user to maneuver freely in a 3D area but using firearms instead of blades. It is virtually useless against Titans, but extremely effective against humans, even if they are equipped with the 3D Maneuver Gear. While the basic principles for maneuvering in it are the same, the design is drastically different: the gear is stored in the upper part of the body instead of on the hips, the user uses their arms in order to reel themselves, and it has high power guns instead of blades.

Usage
The movement is very similar to that the 3D Maneuver Gear. The user just has to aim their grapple hooks at an object, fire them and activate the gas mechanism to reel onto that position. The user can also use their momentum to move not only in a rectilinear pattern but also doing other advanced maneuvers just like slaloming between objects.

Just like the 3D Maneuver Gear, it is less effective in open spaces where the wielder has almost no places where the hooks can be reeled. This fact added to the impossibility of killing Titans with the pistols makes the gear only suitable for man hunting and urban warfare or similar conditions, like the crystal cave located under the Reiss Chapel.

Origin
It was developed by the Military Police in secret as a secret weapon to finish off the Survey Corps. They were first used when the Special Operation Squad tried to follow a wagon to where Eren and Historia were trapped. Levi's squad was attacked by surprise by a team of Military Police that were using the new anti-personnel gear.

Mechanics
Body of the Device - While in the ordinary 3D Maneuver Gear the body is located on the hips, in this model it is located on the upper

back. It is attached to the user's body with harnesses on the torso and arms. The hooks are stored inside the body of two axles that can shoot independently and are fired from the user's arms, not their hip.

Body of the Compressed Gas Cylinder - The Anti-Personnel 3D Maneuver Gear has, instead of two small cylinders, one big cylinder that is also attached to the upper back. This is the part from where the propeller gas is expelled.

Operating Device - The operating device is used to control all the functions of the gear. It is attached at the hands and looks similar to a gun's grip. It has the triggers and levers used to control the movement and the trigger that is used to shoot the guns, which are shot from this part of the gear.

Guns - Instead of blades, the operating device allows the user to attach to them small cannon-like barrels, one to each hand, two at a time. These two hand-cannons can shoot independently and can also be shot at great speed while the wielder is moving. Although they are virtually useless against Titans, these guns are very efficient against humans, even if they are armed with 3D Maneuver Gear. Every gun can shoot one single round with immense stopping power. This indicates that the rounds have an enormous caliber; these rounds can pierce a human head like a watermelon. On the other hand, their penetrating power is limited as they can be blocked with something as simple as a corpse or with the blade of a sword made of Super Hardened Steel. When the rounds have been shot, the whole barrel has to be replaced. The users usually have extra barrels attached to their thighs.

Training
The actual training of the users is unknown, but it is believed that it is similar to training for 3D Maneuver Gear. The greatest difference may be that they are not trained to fight Titans, but instead they are trained to fight against people and shoot their guns while moving at great speed.

Trivia

 * Although the Anti-Personnel 3D Maneuver Gear grants superiority against humans and even the Survey Corps due to it's intense range, Armin detected failures in the design. Due to the fact that both the barrels and the hooks are launched from the hands, a user cannot attack while they are reeling away.
 * Another failure is that the guns may have incredible stopping power, but if the two shots are fired, the wielder has to reload instantly. The 3D Maneuver gear's blades are much more durable.
 * It is unknown if the rounds are shot by using regular gunpowder or compressed gas.
