So I wanted to make a setting where they invented mechs before they invented tanks, and so the tank ended up being the cool new scary weapon to surpass mechs, but I wasn't sure how to go about that. My best three guesses for how to go about that approach are:

1) Tanks are actually an ancient weapon from an era where warfare was less ritualized and more barbaric, and the setting transitioned into mechs as society became more refined and honorable, but now has to figure out how to fight against tanks again from an enemy that doesn't care about honor

2) The society relied on some sort of organic-technology, the mechs were actually partially organic in some way, and since nature has produce legs and arms, but has never produced a tank tread or turret, they just never invented such things until they started building proper full-machine weapons

3) The setting actually has giants in it, and the 'mechs' were actually just power armor for giants that was adopted for human use, and they never bothered with tanks before because it seemed easier to just put a human in a giant's power armor

This is not a thread asking what technologies could make mechs feasible. Quite the opposite. This is a thread asking...what technologies have rendered mechs already obsolete before they ever got a chance to take off? Much like how advancements in gun technology rendered knights obsolete, what technology killed the mech before the mech could even become a thing?

>Wait, are we changing things we do like, or what?
You can change anything you want but provided it is a big enough change to the setting that you wouldn't like it.
