I think it's plausible to identify secondary sources of cheap MCU with eeprom or flash memory from smart appliance that would work in a Russian tank

Hardly you will find anything pin-to-pin compatible around, that could be replaced in the field, really.

May be it is possible to find something for night vision or targeting display system in some industrial equipment, but I can't imagine reballing under the artillery fire.

Tanks electronics replaced by modules, not by resoldering chips, even in service stations. Broken modules sent to manufacturer for proper repair if it is allowed.

(I mean for the type of dumb shit you use cheap like 28-pin type MCUs for in "automotive" type applications.. boring stuff like limit control on a hydraulic actuator... the stuff that does get repaired.. not the high end stuff people picture in their mind..)

You perfectly know, that Russians are retarded, so that modern fashion with doing simple things with MCUs are not yet came in (fortunately ?). In Russian tank limit control for hydraulic actuator will be made without electronics at all. As simple and reliable as possible with minimum parts. Even in newest models.
