In 1990, Gebru Tareke listed the Ethiopian land forces as four revolutionary armies organized as task forces. eleven corps, 24 infantry divisions and four mountain divisions, reinforced by five mechanized divisions, two air divisions and ninety-five brigades, including four mechanized brigades, three artillery brigades, four armoured brigades, twelve special brigades and paracommandos – including the Spartakiad, which was commissioned in 1987 under the direction of the North Koreans – seven missile battalions and ten brigades of paramilitary forces.  When the Derg took control of Ethiopia, they reduced their dependence on the West. Instead, they began to source equipment and sources of organizing and training methods from the Soviet Union and other CAEM countries, particularly Cuba. During this period, the Ethiopian armed forces were often imprisoned in counter-insurgency campaigns against various guerrilla groups. They refined conventional tactics and guerrilla tactics during the eritrean campaigns, avoiding an invasion by Somalia during the Ogaden War in 1977-78.  Reports and statements also indicate that hostilities have reached a level of intensity sufficient to be considered an armed conflict, given the repeated cases of armed confrontation and proliferation in the Tigray region, reports on the weapons used, reports on the weapons used, reports, damage to cities and infrastructure, and the number of Ethiopian civilians fleeing to neighbouring Sudan. TPLF troops also deployed missiles against a number of locations in the neighbouring amhara region and Eritrea. During their operations, Ethiopian government forces used military aviation and threatened to use various heavy weapons, such as tanks and artillery in Tigray. As part of the agreement, freedom of movement is guaranteed for all UNMEE military and civilian personnel. Taxes on goods purchased locally for official use are also abolished under sofa. However, since the outbreak of fighting on 4 November 2020, the Ethiopian army has conducted ground operations and air raids that reportedly focused on attacking the military forces of the Tigray Regional Forces at several locations in Tigray.
International law does not prohibit opposition forces from occupying and using radio facilities (or other civilian structures other than hospitals). However, the presence of opposition fighters or the use of broadcast facilities for military purposes make facilities military targets. In April 1988 Derg reorganized the army. The restoration of relations with Somalia meant that troops could be transferred from the First Revolutionary Army in the Ogades to the second and third Revolutionary Army, the third (TRA) being responsible for the provinces of Assab, Tigray, Wello, Gondar and Gojjam. The very small Fourth Revolutionary Army became responsible not only for protecting the border with Kenya, but also for protecting the border with Somalia and Sudan.
