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 that on the hips, the user used 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 his grapple hooks and 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 to man hunting and urban warfare or similar conditions, like the crystal cave.

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 Squqd tried to follow a wagon 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 in the hips, in this model it is located in the upper back. It is attacked at the user's body with harnesses in the torso and in the arms. The hooks are stored inside the body in 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 cylinder, one big cylinder that is also attacked at the upper back. This is the part from where the propeller gas is expulsed.

Operating device - The operating device is used to control all the functions of the gear. It is attacked 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 the operating device smalls cannon-like barrels, one to each hand, two at a time. These two cannons can shoot independently and can be also shoot at great speed while the wielder is moving. Although they are virtually useless agains titans, these guns are very efficient against humans, even if they are armed with a 3D Maneuver Gear. Every cannon can shoot one single round which inmense stopping power. This indicates that the rounds have an enormous caliber; these rounds can pierce a human head like a watermelon. When the rounds has been shot, the whole barrel has to be replaced. The users usually have extra supplies attached to their thighs.

Training
The actual training of the users is unknown, but it is supposed that they are similar to those of the 3D Maneuver Gear. The greatest difference may be that they are not trained to fight titans, but instead they are trained to combat 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 his intense range, Armin detected failures in the design. Due to the fact that both the barrels and the hooks are launched from the hands, an user cannot attack while he is 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.
