Seven years ago a video went viral of a prototype Russian robot, the ‘FODOR’, dual weilding Glock pistols. For those of us not paying attention at home this technology is notably absent from the war in Ukraine. This is a subtle nod to the fact that the idea of humanoid robots fighting wars is stupid.
Russia has been developing a humanoid robot for several years now. Its primary purpose is to help astronauts during space missions. Since its appearance in the media, there were discussions of how it can be used for military applications. And just recently a video appeared on the internet released by the Russian deputy prime minister Dmitry Rogozin on his social media pages. In the video, they are testing that robot in a course of several unmanned vehicles tests…

Something like a 6-8 leg mech will likely be extremely practical:
Don’t need to open doors or traverse stairs if you shell the building into a pile of rubble.
In the economics of war, if you did need to sweep a building rather than destroy it, risking a few human lives is probably considered an acceptable loss compared to the cost of humanoid robot development and deployment.
You make some interesting points, but allow me to play devils advocate for tanks with tracks:
Can climb stairs and other obstacles (tracks can already do this)
Can manipulate the environment (why open a door when you can just level the whole building, tanks can push objects out of the way especially if fitted with some sort of dozer front attachment, etc)
Cannot jump (armored mechanized vehicles are very very heavy, and getting the kinetic energy required to launch one into the air in a controlled manner will take a lot of energy, batteries would need to be huge or some sort of nuclear power generator will need to be installed, definitely don’t use an engine for that because those forces on an engine will cause catastrophic damage)
Not redundant (while losing a track means the tank will be stuck, it is doubtful that a mech with legs would be able to perform much better. If the mech had more than four legs then maybe, but why cant the tank have 4 tracks? Losing one wouldnt stop the tank either, as it can still make enough contact with 3 to continue in most situations)
Is always prone (mechs with legs will have a taller profile than tanks in most situations, and in cases where a legged mech can go prone to reduce the combat profile the tank will be able to do basically the same thing with a much greater movement speed)
Also, for a moment consider cost. Tanks with tracks are expensive. Theyre expensive to buy and to maintain. However, in comparison to a six legged mecha a tank with tracks will cost comparatively like an econobox car compared to a Maybach.
