The sovjet officers told there hastily trained recruits that they had Anti-Tank-Guns who could penetrant german tanks. They could not. So the tank would drive along the dug emergency trench. One Tankchain in the trenches. They would fire. They would be crushed. Dont remember the length - but about one day of nightmarish driving of this.

It discusses problems with the records leading to difficulties in figuring out such statistics (they go on to model the death rate vs age for the war years).

You can see the pattern you'd expect: a rise in the death rate, compared to the surrounding years, during the world wars. Though there are other peaks, such as the higher peak just before 1920, which is probably influenza, not WWI.
edit: Oh, this doesn't show annual death rate by year of birth, which is what you were looking for
700/1,800 = 38%
Still, 38% is pretty bad.
