Sounds like the (British) redcoats during our American revolution, who complained that they were getting picked off in the field by hidden American patriots - and wanted the American patriots to play be the THEN "generally accepted rules of field infantry engagements," by presenting themselves in similar marching line(s), out in the open.
Of course, the American patriots would have nothing to do with this absurd expectation. After all, what better opponent target opportunity could there be, than a bright red and white uniform, as worn by the British forces, marching in an advancing line towards the hidden American patriot lines - so easy to see, so easy to hit - from up in the tree-line, naturally obscured/blended into the surrounding environment - American patriots dressed in their earth-tone buckskins, etc.
The Russians are correct - who says that they have to "play" by some "rules" that massage western sensibilities regarding the exchange of nuclear weapons?
In war, there may not be any rules that can be relied upon, by ALL sides/stakeholders - the military machines, the people, the politicos, the economic stakeholders.
