Returning from the front, Berlinska founded a free school to train other Ukrainian military volunteers in aerial reconnaissance.

Beginning in 2015, Berlinska partnered with other female volunteer soldiers to champion women's rights and integration into the Ukrainian Armed Forces.

[1][2] In her spare time, Berlinska played guitar, and co-organized the annual Respublica [uk] music festivals with bands such as Lyapis Trubetskoy and Skryabin, using part of the profits to pay artists to decorate houses in Kamianets-Podilskyi.

The court ruled that she had proven her case, but then the Ministry of Defense appealed and won, since, despite witnesses and photo and video evidence, there were no written orders.

[23] The report found that female soldiers were forbidden by law from holding military commands, did not have basic needs met, and, despite some women being in combat roles, were all categorized as support personnel.

[21][24] As a result, female soldiers did not receive the same salaries, legal protections, compensation for injuries, post-combat trauma care, and opportunities for career advancement in the military as male personnel.

[28] In 2017, Berlinska organized and produced a documentary film also titled Invisible Battalion, profiling six female soldiers who served in the war in Donbass without being recognized for it: Yuliia Paievska, a paramedic; Yulia Matvienko, called "Belka", a sniper, officially listed as a medical assistant; Olena Bilozerska, another sniper, never officially enlisted; Oksana Yakubova, suffering from post-traumatic stress disorder (PTSD); Andriana Susak, who fought to retake Schastia while wearing a balaclava to hide her gender, and was officially listed as a seamstress;[28] and Daria Zubenko, paramedic.

[32] In 2018, Berlinska produced the sequel documentary No Obvious Signs (Ukrainian: Явних проявів немає; referring to the fact that psychological trauma is not as visible as physical wounds), directed by Gorlova, about Yakubova's struggles with PTSD.

It was a multifaceted campaign, beginning with an anonymous survey of male and female veterans, which showed that 70% had witnessed or been the victims of sexual harassment in the military.

[44] There was an online course on the Prometheus educational platform titled "Gender equality and combating sexual harassment in the military sphere" (Ukrainian: Гендерна рівність та протидія сексуальним домаганням у військовій сфері).

[46] A chatbot running on the Invisible Battalion web site enabled military personnel to receive information and psychological and legal assistance about sexual harassment completely anonymously.

[51][52] In addition to mutual support meetings, the NGO provides psychological rehabilitation for women veterans suffering from PTSD and substance addiction, conducts online training in business, management, and IT courses, helps with gynecological services, and has planted five "Alleys of Memory" in honor of dead women veterans in Kramatorsk, Kyiv, Lviv, Cherkasy and Zhytomyr.

[49] In September 2018, the Ukrainian parliament passed law 2523-VIII equalizing the capabilities of men and women in the military; Berlinska was a co-author.

[60] In July 2019, the Embassy of the United States, Kyiv included her in an exhibit paying tribute to 19 Ukrainian and 29 American outstanding women.
