OOC Is Serious Business / Girls und Panzer

• Mako is typically coolheaded at her most energetic and lethargic and lazy at worst. When she hears about her grandmother collapsing, she becomes especially determined to reach the hospital as soon as possible, even considering swimming an impossible distance if necessary.
• Mako, who detests having to get up early and is often shown napping, is said to be losing sleep over her grandmother's condition, since the previously mentioned collapse is not the first one.
• Mako typically snarks at Sodoko, calls her by her nickname against her wishes, and displays a calm and stoic personality. When Sodoko deletes all of Mako's tardinesses and absences, ensuring that she will be able to graduate on time Mako lets out a whoop and glomps her.
• Katyusha is quite arrogant, and enjoys sitting on the shoulders of Nonna to seem taller than everyone else because of her short height. When she's defeated by Oarai, she gets off Nonna's shoulders and shakes Miho's hand, something she had refused to do earlier, to congratulate them.
• In the Little Army prequel manga, Miho, upset by Maho's aloof behavior after admitting to having shot an enemy flag tank when it went to rescue one of hers, questions her mother on whether it was necessary, despite her timidity and unwillingness to call her own mother out. Her mother shrugs this off, but Maho makes note of this and later comes to speak with Miho privately to apologize and tell her to pursue her own style of tankery.

  Maho: I was surprised today, to see Miho talk to Mother like that. That shows you were quite desperate... I'm sorry.

• Momo typically alternates between being relatively calm and getting comically angry over things like missing or being called "Momo-chan". On some occasions, though, she seems genuinely upset, such as when the team doesn't care whether or believe they can win, especially considering the school will be shut down if they don't win the tournament.
• Miho is generally a polite girl who can't find it in her to say anything bad about other people, even the Jerkasses. When Emi begins saying she hates Miho's sister despite never having gotten to know her, Miho loses her temper and, in her anger, declares she hates Emi. Miho's friends are shocked at how Miho got angry, and Sakuyo notes that it's rare for Miho to get angry.
• Anzu is typically a Perpetual Smiler, generally loses the smile under similar circumstances as Momo's own OOC Is Serious Business behavior.

  Anzu: (not smiling) Losing is not an option for us...
  Yukari: (thinks) The president became serious for once.

• After Saunders loses to Oarai, Kay, typically a cheerful Large Ham who likes competition, walks up to Arisa, whose unsportsmanlike intercepting radio transmissions backfired and cost them the match, and tells her in a calm, yet stern tone of voice that they will be discussing what happened, prompting an Oh, Crap! reaction from Arisa.
• Maho, typically stoic and outwardly unquestioning of her mother's methods and beliefs, expresses her opinion about Oarai High School's victory over Pravda High School when said mother states that Oarai only won because Pravda became careless. Notable as her opinion is the opposite of her mother's, stating that Oarai won because of clever tactics and strategies and that Miho, who is viewed by their mother as a failure and a disgrace to their traditional sensha-do practice, is as skilled and talented as herself.
• In the anime's final episode, the perpetually stoic Maho smiles as she congratulates Miho for winning the tournament despite seemingly insurmountable odds, especially since Miho won against her. Notable in that despite her loss, Maho is proud of her younger sister for finding her own take on sensha-do, which was what Maho wanted for her since the beginning.
• In Der Film, Shiho, who's generally calm and composed, slams her glass down on a table while telling the official who reneged on his promise to keep Oarai open if they won the tournament, that there's no luck in sensha-do, implying that Oarai (which Shiho otherwise looks down upon) deserved its victory.
