My mind still occupied by anime story line before,when i search about its so different
"Though the anime follows closely to the original source, it markedly highlights the brutal and cruel side of Tanya's character. This can be seen from a number of differences in her monologue and action. In the first episode, Tanya purposely arranges the death of two insubordinate soldiers under her, while in the original source, they are simply taken off of her platoon to prevent discord"
And of course i don't mean to say she plan it with enemies
