The previous 62nd Signals Brigade at Gorna Malina was responsible for maintaining the higher military communication lines. Next to the functions of the Signals Regiment in the Sofia suburb of Suhodol, the brigade had at least three dispersed "signals regiments for government communications", such as the 75th Signals Regiment (Lovech), the 65th Signals Regiment (Nova Zagora) and at least one additional unknown Signals Regiment in the Rila-Pirin mountain massif. The modern successor of the 62nd Signals Brigade are the Stationary Communication and Information System ("Стационарна Комуникационна Информационна Система" ("СКИС")) of the Defence Staff (which fulfills also the tasks of SIGINT and Cyber Defence next to its strategic communications mission) and the Mobile Communication and Information System ("Мобилна Комуникационна Информационна Система" ("МКИС")) of the Joint Forces Command.
