>IRL mecha
You guys just don't have enough imagination and are stuck with the current doctrines and OLD war lessons.
Even as we discovered that tanks are obsolete, that drone are also expandable against any air-defense, and so on.
Eventually we will have AI-turret that instantly one-shot incoming drones, missiles and unprotected soldiers.

I could justify manned mecha on Earth, but it's easier with a space setting.
- low gravity is horrible for wheeled/tracked vehicles
- in 0 gravity you can't even move without propellant unless you grab and push
- on new planet you do not have 1000y of roads building to help you
And if your civilization is fragile enough that any damage will kill millions, you can even justify very close combat.

>Basically for mechs to work we’d need something that relies on humanoid shape and literally nothing else works.
I'm sorry to tell you but that's just you being retarded.
It's not even the humanoid part, that's EASY to justify as soon as you can do reliable bipedal balance, and arms are useful.
The retard part is you thinking mecha are distinct units using alien-tech instead of the result of the technological level of everything else.
