Though legs were far superior to treads and jet pads, if you could build anti-gravity hovering devices, what did you need legs for?
Arms had no reason to exist either. Mechanical arms were extended to hold weapons, so why not just mount the weapons directly onto the torso? It would even save the effort of manufacturing high-precision mechanical arms.
There was no need for something like a head either. If it was only meant to integrate observation systems and radar equipment, it could simply be flattened and stuffed into the body.
Was the massive size meant to increase the target area? Of course not. It should be designed as small as possible.
In the end, after comprehensive consideration, the finished mech blueprint looked no different from a tank.
"But Titans and Knights really were designed by you people, weren't they?"
"Ahem... Back then, we never intended for them to fight real wars. Since the Human Federation was founded, there had only been three proper wars. One was the extermination of the Ork Empire, while the other two were clashes with the Aeldari Empire. We never once used things like Titans against them. My suggestion is that, instead of building mechs, we should build cheaper tanks and exoskeletons."
Oedmeir rejected Lin Fan's proposal to build mechs and began considering what kind of war equipment the current universe actually needed.
The Orks and Tyranids were numerous and thick-skinned, Chaos corruption seeped into every crack, and Warp daemons existed in defiance of physical laws.
The new armor needed to be cheap and plentiful, possess enough firepower to charge in and out of enemy masses seven times over, and carry weapons capable of harming daemons.
Ah... What a pain... If this were before, she would have stuffed an AI combat system into a tank,
