Ukrainian guerrillas constantly carry out activities harassing Russian business troops, which we learn about from various sources, including online ones. However, it must not be forgotten that actions behind enemy lines are not limited to physical acts of diversion towards bridges or railways.This is simply a full scope of forms of putting force on the opponent (in this case Russians and collaborators), as well as building the essential intelligence facilities for their own troops. At the same time, the civilian population under business is in contact with the activity of their own authorities and is aware that the business is only a temporary state. However, the importance of irregular actions cannot be overestimated and request from the Ukrainian guerrilla a kind of mass uprising in areas occupied by Russian troops.
