Tunka-Grande and TAIGA-Muon scintillation arrays are part of the TAIGA astrophysical complex. This complex is located in the Tunka Valley (Republic of Buryatia, Russia), 50 km from Lake Baikal and is aimed at solving fundamental problems of cosmic ray physics and gamma-ray astronomy. The article provides an overview of the Tunka-Grande and TAIGA-Muon arrays. Main results obtained from the experimental data of the Tunka-Grande array for the first 5 years of its operation are presented. The prospects for studying primary cosmic radiation in the energy range 10^14 - 10^18 eV are discussed.
