For starters, fire can disable even modern military vehicles. That's why they have suppression systems in place. Secondly, as FRAMEs are powered by nuclear reactors I'd assume heat mitigation would be even more of a concern, especially when one considers the heaviest starting FRAME weighs 'only' a tenth of an M1 Abrams.

Speaking of vulnerabilities, I've been meaning to ask [@Aristo], are the air intakes, reactor and such housed in the torso as well as the cockpit? Or are the distributed across the FRAME's whole? Likewise is there enough interior space to house ammunition or would it be mounted externally as part of a weapon system? Do pilots enter from the front or back torso? Finally if the external cameras were disabled or destroyed do FRAMEs have any sort of fallback system, like a periscope or other low-tech solution? Given how you describe them being operated I'm not sure they could be driven with an open or ajar cockpit.
