The Orlan-10 reconnaissance drone is used in the video released by Russia. Leer-3 is a GSM communication jammer, that blocks the mobile phone network. This electronic warfare complex can send messages, better known as Short Message Service [SMS], Russia claims.

Leer-3 detects mass crowding of cellular phone subscribers to a given network in real-time. Since the beginning of the war, Ukraine has skillfully moved and hidden its GSM clusters and terminals in forest plantations, riverbeds, village huts, etc. The Leer-3 suppressor is looking for just that. Once located, the coordinate data is sent to the headquarters of the nearest mobile electronic warfare unit.

These divisions make decisions about what to do with discovered GSM terminals and clusters. There are two possibilities – jamming or hacking them and using them to transmit short messages. The Russian Federation does not hide that they use “psychological pressure” on both Ukrainian fighters and the civilian population.

SMSs are sent that often read “The Armed Forces of Ukraine are preparing a provocation in your city. Do not leave the house. Take care of yourself and your loved ones.”

The use of the Orlan-10 along with the Leer-3 shows that the Russian armed forces are trying to jam communications in critical areas. In this way, the effectiveness of the Ukrainian command, as well as the management of troops and weapons systems, is reduced. has no information on how successful this Russian technology is. Information so far about Leer-3 comes only from Russian channels, without confirmation of its effectiveness from the other side – Ukraine.

On 24 February 2022, Putin ordered an invasion of Ukraine by Russian Armed Forces previously concentrated along the border. The invasion followed by targeted airstrikes of military buildings in the country. The invasion followed also by targeted tanks entering via Belarus border.

Russia has so far not recognized the invasion of Ukraine as a “war”, although that is exactly what it is, claiming that it is a “special military operation”. According to the UN, in which Russia has its permanent representation, for military action to be defined as a “special military operation”, it must have a resolution issued by the UN. There is no such resolution, which automatically defines the military actions of the Russians as an invasion and war against the citizens of Ukraine.
