False Flag by Rachel Churcher

Two young women. A dis-united Kingdom. Opposing sides in a British civil war. Ketty Smith is an instructor with the Recruit Training Service, turning sixteen-year-old conscripts into government fighters. She's determined to win the job of lead instructor at Camp Bishop, but the arrival of Bex and her friends brings challenges she's not ready to handle. Running from her own traumatic past, Ketty faces a choice: to make a stand, and expose a government conspiracy, or keep herself safe, and hope she's working for the winning side. The Battle Ground series is set in a dystopian near-future UK, after Brexit and Scottish independence. 'This series is raising the standard for YA dystopian fiction, and I can’t give it less than 5 stars' - AyJayPageFarer Book Blog
