Tanya is a very complex character. In her past life, Tanya described herself as someone with many complexes and that he was twisted. She has both superiority and inferiority complexes, which is shown by how she compared herself to real geniuses she couldn't compete with, while also desired to be above others. Tanya has a lot of sociopathic traits; cold, calculating, and often sees others as objects she can use to her advantage. This allowed her to rise rapidly through the ranks of her careers in both lives. Tanya places her faith in numbers, following the Chicago School of Economy, which states that everything has a price. This could be seen from how effectively she picks and raises her subordinates to be a valuable human resource she can use. This also allows her to become a very efficient commander as she is both a decisive strategist and cunning tactician who is not hindered by her emotions. Tanya also sees herself as a profitable human resource, doing everything to raise her value in the eyes of her superiors, which drives her to put up a front of the perfect soldier since her recruitment. This impresses and also unnerves her comrades, particularly Erich von Rerugen, who considers her a psychopath for her ruthlessness. Sometimes, this trait also becomes a disadvantage to her, such as her lack of empathy that disables her from putting herself in other people's shoes. In particular, her lack of insight of possibility that the people she offended by her callous dismissals would take revenge on her. She is also a libertarian, as it could be seen from her monologue about freedom of will and goal for a comfortable life in the rear. Something she had sought in previous life, too. This trait of personality is also the source of her frustration on how the Imperial Army treats their soldiers, in which mission is an absolute and she couldn't disobey even suicide missions. It's also why Tanya loathes Being-X for disrespecting her freedom and intending to convert her even against her will. Due to her faith in signaling theory, Tanya dons a mask of the perfect soldier. On the surface, Tanya is every bit what an Imperial soldier should strive to be. A harsh disciplinarian who still cares about the lives and safety of her troops. A stupendously powerful and brutal warrior that still adheres to international laws. A person with a sharp tactical mind, unflinching courage, and unquestionable loyalty to her country. An officer who nevertheless remains humble and respectful to even non-commissioned officers. A devout believer in religion who often calls upon God to bless her country. All of these would make her an inspirational figure, the fact that she is a young girl only makes the adults around her vow to work harder. Tanya has an iron-clad belief in her ideology and methodology, which is also why she is oblivious of the fact that what she did in her previous life didn't give the same result in her current career and timeline. More often than not, she has assumed other soldiers would share her mindset, such as refusing to apply for a dangerous assignment, leading her to a series of failures in achieving her goal. While she did notice she didn't get the results she wanted, Tanya stubbornly believes her method isn't the reason.
