Unit 54777, alternately called the 72nd Special Service Center, is one of the GRU's primary psychological warfare capabilities. Unit 54777 retains several front organizations, including InfoRos and the Institute of the Russian Diaspora. The unit originated from Soviet GLAVPUR ("Glavnoye Politicheskoye Upravlenie", or the Main Political Department) and was created in early 90's and notably employed colonel Aleksandr Viktorovich Golyev, whose memoirs were published in 2020 along with other GRU documents. In 90's the unit was focused on pro-Soviet disinformation in newly split republics such as Lithuania and Chechnya. In later years the unit covered a broad range of activities from running NGOs targeting Russian expatriots in Western countries (InfoRos, Institute of the Russian Diaspora, World Coordinating Council of Russian Compatriots Living Abroad, Foundation for Supporting and Protecting the Rights of Compatriots Living Abroad) and manipulating public opinion in Russia and abroad in preparation for armed conflicts such as in Georgia, Donbass or Syria.
