The Defence Ministry said soldiers and military vehicles will travel on national roads and railways today and on 12 October.
They belong to the 2nd Tundzha Mechanised Brigade and the 5th Brigade Command of the Land Forces, and are returning from planned training at the Koren and Novo Selo firing ranges.
Military police teams will escort the convoys.
In September, troops and vehicles from Turkey's armed forces also moved along Bulgaria's national road network.
