That was likely my comment, most likely in that militarism thread. The USSR unlike the USA suffered severe, direct consequences in the 2nd world war and combined with the socialist system, this imprinted firmly the idea that war is horrible and necessary to defend oneself.
It's why the USSR was hesitant to involve its own troops in foreign conflicts while the USA threw away its soldiers everywhere with wild abandon. The idea of someone going gung-ho into a battle and killing all the nazis in gory detail without any care, while bullets miss him like a video-game cheat... its an inconceivable falsity to soviet people, that trivializes real heroics and discredits their enemy. How can you be heroic if your enemies are all incompetent retards anyway? Moreover death, any death leaves an imprint, it is supposed to, if you don't feel anything at the sight of people killed, then that's just sociopathy and if you (as an adult) find it fun, then that's psychopathy. Death is never trivial and to find amusement it is to trivialize it. To cheer it on, deservedly or not, is to be like an uncivilized chimp, hooting and hollering when an alpha beats another male to death with a rock. My Grandfather told me the story of how they liberated a village that had been under the SS. Two SS officers were captured. They had killed every man in the village and many women and children were murdered by them. All that was left were some older women and a few remaining children. They were so furious and angry that they beat the officers to death with rocks in a rage, in revenge, for their families killed like animals. And nobody cheered, nobody laughed, nobody was feeling cool or happy about this impromptu execution. Afterwards the women cried bitter bitter tears as they still could never return their beloved papas, mamas, daughters and sons. They were gone forever, and they would live the rest of their lives with that aching gap in their hearts. That is what the film Come and See depicts with complete accuracy.
War is misery, war is death, war is anger and hate and sadness with tears and blood and bile. There is no glory in war, only outside it, when your sacrifice is acknowledged by the people and remembered. There is bravery and valor, but within every soldier who fights, that exists because to put your life on the line requires this.
I've gone on a bit of a tangent, but it is necessary. Too many people on this site think that killing someone, nazi or not is easy or guiltless or good. Too many people think that shooting guns around in wild abandon is a good idea. Too many people here LARP about fighting, yet know nothing about it or the bad things it brings.
I leave you with this, not a single song about the actual war in the USSR was happy or cheerful. The navy and artillery and tankists may have had their peppy marches, but not a single song about the war itself celebrated the war. Cautious optimism was the best you would get from their songs.
