Jest you got confused, you quoted yourself.
Of course but I was not being serious or not entirely. Your view of the Russian, however, is pretty simple and I would say false. During WWII Russian were using more snipers than anyone else (they still do). They used 14.5 rifle as soon as 1942. At Kursk they used a multi-layer defense that destroyed massive attacks by the Germans.
They use mass fire when employing low level soldier but that is true to everyone. Things might be changing as most armies are now professional troops, highly trained. That would not remain as such in case of global conflict as you would have to rely on less trained troopers (in my opinion).
At a tactical level what you say is true for everyone, at a strategic level everyone use as much power as it can to the soldier dismay usually. You gave the Somme as an exemple but there are several more recent ones: Stalingrad, Monte Cassino, Berlin, Beyruth (1982), Falloudja...
