Pg 4Trial History of Early Walking Combat Machines
The Development of the initial walking combat machines, the E.T..
E.T.01 Mk II Spider
It is the initial type of combat use E.T.. Two large 80 mm rocket launchers are attached to the body, which house 40 missiles each. It is said that it's maximum walking speed is at the 30 kmph level.E.T.01 Mk IV Tarantula
It's equipped with 4 medium range surface to air missiles, and 2 short range surface to air missiles. The air surveillance radar gives the impression of the future Destroid Defender. The lower side of the body is equipped with a machine-gun for close range combat.E.T.01 Mk V Black Widow
In the final type of E.T., armaments have been strengthened and the payload has been improved. On the body are a double-barreled 180 mm recoilless gun. Moreover, the "arms" are equipped with supplemental 3 barrel 50 mm rocket launchers.Outline of the Development of the E.T:
The thing which is able to say that it is the prototype of the first walking combat machine (which comes to be named Destroid) in the history of mankind, and whose development had started in the early 1990s, before the fall of the Macross. We're introducing them here; however only one, which was a phantom bird-legged walking type of craft, was left behind and has vanished.
Though the initial, experimental walking machine was named W.V. (Walking Vehicle) at first, it was soon changed to E.T. (Earth Trekker (ground walker)). The origin of this code is this machine's tottering way of walking and moving on it's short legs; and it is said that its movement looks like the hero of a certain movie that became a worldwide hit in the 1980's. Though the details are not certain.
This one series in the series (of early walking machines), is the pioneering existance of what later became the development of the Destroids.Caption:
It is understood that the center of gravity (of the Earth Trekkers) is much lower compared to the Destroids.

At the same time as the Combat use E.T., there was also a trial manufactured work type of E.T., which had what could be called the first "arm" on an E.T.. After the discontinuation of E.T. development, it continued to be used for a while. A small number where sold to private organizations, where they were they played an active role.DTR 03 Mk I Dinosaur
The large-scale craft, trial manufactured to make use of a large payload capability on a bird-legged type of E.T.. It is equipped with 2 sets of 5 barreled 200 mm rocket launcers and so on. This type became the ancestor of the "Monster", the only future bird-legged type of Destroid.Outline of the Development of the E.T: con't
An improvement in an armoured vehicle's ability to penetrate irregular ground had been tried in various shapes in the latter half of the 1970s.
The method like the M1 tank of the USA, with a new, high powered engine, such as a gas turbine and so on, as well as a structure of two tanks tied front and back like the Swedish UDES-XX-20, which was a method to give a kind of movement like a living thing.
And, in the mid-1990's, the MBT-97 "Fubirai" tank, which aggregates these two methods, is completed and was assumed to be the definitive edition of the caterpillar [tracked] type of tank.
However, at that time a certain country's military must also say the next level, and as a means of a rapid improvement in ability, had started the walking system research.
As for this, the military knew of a thing being secretly developed as a public works machine by a certain vehicle manufacturer, and was the one that was surmised as being able to be put to another use as a weapon.
As for the ambulatory [walking] system, though at first it was thought of walking like the theropod walking type where the knee is lifted like a man, beast and so, it was expected to create a large difficulty in development. For the time being, development proceeded in the bird-leg walking type, where the tiptoe was lifted like a bird.
As for the merit of the bird-leg type, compared with the theropod type, because the range of motion is smaller, it is able to have a more sturdy joint, with a simpler structure. The structural build-up of the entire leg is also simpler, and it was able to support the large weight of the body. Moreover, the movement range of the centre of gravity when walking is clearly less, and it enabled the E.T to move at a higher-speed than the theropod type.
However, because the auto-balancer was still undeveloped at this time, it was a catastrophe that the centre of gravity couldn't be raised very high. The short leg was an ability break-through into unsacred ground, and the ability was not very different from the caterpillar [tracked] type (of land vehicle). As well, the speed wasn't as much as was thought and a weakness was identified which had said that a constructional retreat was difficult. In the end, the development of the E.T was discontinued.
As for the appearance of a practical type of walking machine, it was necessary to wait until the 21st century, when mankind obtained over-technology.
