The MS-05 and sniper variant. There were other "variants" but there wasn't much difference.. the command version had an extra shoulder dome and paint job (not really enough to make stat difference).
MS-05 Zaku I
The MS-05 Zaku I is considered obsolete, but still an effective and cheap mech, with improvements over the MS-04 in materials used, targeting systems and available weapons. There were also two variant models of the MS-05 produced: a sniper variant and a command version. The 05 saw improvements in the hands, including an induction connection to allow for powering the heat hawk/axe, although a shield was not included in the base model to save on weight and cost, it can make use of the 04's arm shield, or the 06's shoulder shield. The 05 is also compatible with many weapons later produced for other Zakus and mechs produced by the Principality of Zeon. It comes standard with a modified M-9 Barrage that uses magazines and a holster mounted on the shoulder, this allows the hands to be free when not in combat. Alternate weapons available are a bazooka, a mech sized shotgun, a heated axe and can carry grenades.
Standing at only 57.5 feet, and weighing about 50.3 tons, it isn't the largest of mobile suits, which does give it some other advantages that it may lack from technological means.

This weapon has become the standard melee weapon on Zeon mechs for many years. The heat hawk deals half slashing and half heat (fire) damage based on the size of the mech wielding it: Large 2d12, Huge 3d12, Gargantuan 4d12, Colossal 5d12. The heat hawk also ignores 5 points of hardness/DR.

Optional Weapons
The Zaku I MS-05 can make use of most Principality of Zeon mech weapons produced for other mechs, as long as they do not require a dedicated power source, such as beam weapons, unless they have independent power packs. Such weapons include knuckle shield, grenades, the shotgun used by the MS-18E Kampfer, etc.
280mm Bazooka
This is a single shot heavy missile weapon that can be used by most Zakus and other mechs produced by the Principality of Zeon. Although other users have adapted it for use by other mechs. Designed like a very large RPG-7, a large tube launcher that must be reloaded after each attack. Deals 10d8 points of fire damage to a 30 foot radius burst, and ignores 15 points of hardness/DR on the initial target hit. The bazooka itself only holds one round, and each equipment slot dedicated to ammunition holds 4 missiles. Takes a standard action to load the bazooka, which provokes an attack of opportunity. The Bazooka is inaccurate and suffers a further -2 to attack. It can be fired one handed, but suffers a further -2 to attack.

Variant Designs
Zaku I MS-05L Sniper Type
A variant of the MS-05 that is reequipped for sniping purposes. It can also be used for reconnaissance purposes with its enhanced sensors.
The head was redesigned with improved sensors, and includes a light projectile weapon that can be used against infantry or for defensive purposes such as shooting down missiles, or attacking lightly armoured sensors of other mechs. The Sniper mounts a special backpack unit that includes its space thruster, although with reduced power, and a secondary power source for powering an energy ranged weapon.

Beam Sniper Rifle
This energy weapon requires a dedicated energy source, which is the Zaku I MS-05L's modified deep space thruster back pack, which can be ejected in an emergency, but leaves the weapon useless. This energy weapon is highly accurate, long ranged and powerful, but if fired too rapidly, it can overheat and malfunction.

Vulcan Weapon
This weapon system is a rapid fire ballistic weapon used for anti infantry and can be used to attempt to shoot missiles, but usually a back up weapon. If used to shoot missiles, it has a 20% chance to shoot down missiles that attack the equipped mech, and uses 10 rounds of ammunition. Each time the system is used to shoot down missiles, it incurs a cumulative -1 to ranged attack rolls due to the head turning to bring the weapon to bear. As a weapon, it deals 3d8 points of ballistic damage.
