During her military career, Knight served in Germany with the 26th Regiment Royal Artillery, where she was the only Black woman in her entire regiment.[3] She also earned the rank of Corporal, and in 2021 she became an instructor at the Army Foundation College.[2]
In 2019, Knight became the face of a British military recruitment posted titled "Me Me Me Millennials. Your Army Needs You and Your Self Belief."[4]
During her time in the military, Knight claimed she became the victim of bullying and sustained sexist and racial discrimination which Knight began to secretly record. This included fellow soldiers allegedly making watermelon stereotypes towards her, threatened to hotbox, made jokes about tarring and feathering her, and repeatedly called her a "black bitch".[2] Knight also claimed some of her fellow soldiers professed support for racist organisations such as the Ku Klux Klan, Britain First, and the English Defence League.[5]
During her training, Knight was reprimanded by a senior soldier for the style she wore her braids and told "this isn't the ghetto". In 2013 Knight was assaulted by a senior colleague in an attack that was suspected to have been racially motivated. While stationed in Germany she was told to avoid a corridor because her fellow soldiers had displayed swastikas and Confederate flags. While working in the Army Foundation college, fellow soldiers stacked dirty items and boxes on her desk and loudly played Django Unchained when she was nearby, and the instructors posted photos of penises and Adolf Hitler on the professional WhatsApp group which she was a part of. She also claimed male soldiers threatening to lynch her.[1]
When Knight brought evidence of the abuse to her superiors, she was removed from her role under the guise of protecting her mental health.[6]
