It is also disingenous to call Russian revolution a "Labor action", since it was performed first by army generals and members of ruling class, then by political exiles-in-return.
122,000 killed, wounded, or captured. And that was just one battle.

The Russians lost 30,000 killed or wounded, while the Germans sustained a total of only 13,000 casualties. Some 92,000 Russian prisoners were taken, two and a half army corps annihilated, and the remaining half of Samsonov’s army severely shaken.
Moreover it has mostly uprooted the surviving rest of society.
That trauma has dwarfed WWI and almost erased it from public memory.
When it comes to politics, in particular, WW1 is remembered precisely because it led to a revolution, and it was very obvious and explicit in the revolutionaries' rhetoric; one of the most famous slogans was "штыки в землю", literally "bayonets into the ground".
It's mostly forgotten in the US, for that matter. I think the last living veteran of that war died recently. Peter Jackson's recent cleaning up of the movie footage for "They Shall Not Grow Old" https://www.imdb.com/title/tt7905466/?ref_=nv_sr_srsg_1 was heart-rending.
Even I hear of Women's Death Batallions for the first time. Need to google.
There was a Russian Civil War, which we don't hear much about. So the war hadn't really ended for them. There was also a war between Russia and Poland.
I looked some for a total of "WW I casualties by year" table but didn't find one; only "casualties by country." The significance would be "giant German offensive; therefore giant casualties."
In any case, I don't think there's much of a case for the hypothesis "Russian Revolution saved lives."
