The Hizack is outfitted with a titanium alloy ceramic composite armor, and has a higher output generator than that of a Zaku. It is also faster and more agile than its predecessors, and is easily controlled by its pilot. The Hizack is most often equipped with an 120mm machine gun kai, beam saber or heat hawk. Sometimes, it is equipped with a beam rifle, but it has fairly low tolerance for beam weaponry due to its low energy output, meaning it can only carry one at a time. The Hizack can also be equipped with missile pods.
Mounted on the right shoulder, it is a simple defense used to block most physical projectiles.
An axe-like weapon used by the original MS-06 Zaku II, whose name is short for "tomahawk". Thermal energy is relayed through the mobile suit's hand to heat the heat hawk's blade, allowing it to slice through the armor of enemy warships or mobile suits. Although the Hizack normally use a beam saber, it would have to use this if it was using a beam rifle due to its low-output generator.
The beam saber is a small device held in the mobile suit's hands when deployed and is powered by a rechargeable energy capacitor. It emits high-energy Minovsky particles to form a blade-shaped I-field (via manipulation of electromagnetic fields), and then fills this I-field shell with superheated Minovsky particle plasma to produce an effective cutting blade for close combat. However, it couldn't use it in conjunction with its beam rifle due to having a low-output generator.
3-tube Missile Pod
The Hizack could optionally mount a pair of 3-tube missile pods on each side of its hips for long to mid-range attacks.
BR-87A Beam Rifle
A standard hand carried ranged beam weapon is the beam rifle. This particular model is same as the one used by the Marasai, however, the Hizack's low generator output hinders its effectiveness. It is powered by a replaceable e-pac and is power rated at 2.2 MW.
A model of shield popular with Hizack pilots, it is mounted on the left arm. Shields are simple in their design, being essentially thick slabs of armor that the mobile suit can use to absorb the impact from attacks that, for whatever reason, cannot be dodged. However shields can only withstand so much pressure before becoming damaged themselves. The back side can store two spare e-pacs for the beam rifle.
120mm Zaku Machine Gun Kai
A recreation of the original Zaku II's machine gun, in order to provide a cheaper and less energy-consuming weapon. It is a shell firing gun that does not require energy to be used, however its effectiveness against heavy armor is very limited. Features an improved stock and improved accuracy with a federation standard sensor.
135mm Anti-Ship Rifle
A long-barreled weapon used for long-range sniping attacks. It fires highly accurate solid rounds which can heavily damage warships. Appears on a customized Gunpla in episode 6 of Gundam Build Divers.
Special Equipment & Features
An atmospheric entry device designed to be used by a Mobile Suit. As the mobile suit enters the atmosphere, a bowl-shaped ballute (balloon parachute) deploys to protect it from the friction heat of atmospheric entry. The balloon then detaches, leaving the mobile suit with chest and leg hover units which ease its descent to the ground. If the mobile suit reaches the ground without expending all the fuel in the leg units, these devices can also be used for hovering and high-speed strike missions. The equipment was designed and mass produced between the years U.C. 0083 and 0087 and is designed to be used by a multitude of different mobile suit models.
Mobile Suit Zeta Gundam
The RMS-106 Hizack is the first mass production mobile suit brought into the world by Anaheim Electronics. Its external appearance resembles that of the famous Zaku II series used by the old Principality of Zeon forces, and this design could only have been created by Anaheim, which has absorbed the Zeonic Company which was once Zeon's major mobile suit maker. Zeonic's development know-how is incorporated in the machine's inner construction as well as its outward appearance, giving it the same high operating reliability and ease of production as the Zaku II. Naturally, it can use beam weapons, and it's the first mass production machine to include a linear seat and panoramic monitor as standard equipment.
Hizack mobile suits served as one of the three main mobile suit models that filled the Earth Federation forces' ranks from 0084-0087, alongside the RMS-179 GM II and RMS-117 Galbaldy β, and was the primary mainstay mobile suit of the Titans organization until the RMS-108 Marasai was introduced. As the main unit of the Titans the Hizack was used in many missions to eradicate anti-Federation dissidents. By 0087 the Hizack was primarily pitted against the AEUG and Karaba organizations, however time and again it was proven that the rebel pilots and machines were simply superior to the Hizack. In the same year, the Hizack began being phased out as the Titans were supplied with newer machine developed by the Earth Federation, Anaheim Electronics, and their own research teams.
Mobile Suit Gundam ZZ
The Hizack was originally built and operated by the Earth Federation Forces, but the invasion of Earth by Neo Zeon during the First Neo Zeon War resulted in several of these units being captured by the enemy. Though it is likely that some Earth Federation combat units possessed Hizacks they were no longer one of the Federation's primary mobile suits, having been replaced by the RGM-86R GM III, and MSA-003 Nemo. It is likely that use of the Hizack ceased because of its association with the Titans.
Mobile Suit Gundam: Char's Counterattack
By U.C. 0093, the Hizack had been almost completely phased out and, as such, was either being used for scrap or for private purposes. One of these variants was the RMS-116H Hobby Hizack, a civilian use variant.

Notes & Trivia
In SD Gundam Capsule Fighter Online, the Titans-colored and EFSF-colored Hizacks showcase the unit's low tolerance for beam weaponry: the common Titans-colored Hizack is outfitted with a beam saber and the Zaku machine gun while the rare EFSF-colored Hizack is outfitted with a heat hawk and a beam rifle.
