Well you ask the civilian population to leave , then any resistance pocket can be remotely incinerated . And it is not difficult to evacuate cities ; this happens naturally , when there is fighting in and around cities . The noise of explosions , blocked Roads and constant life in shelters will force many to leave . The important tactic is to encircle the bulk of the UA and disarm them , as well as extremist pockets in towns . This ensures that , they can not escape with their weapons and carry out insurgency later on . Bypassing many towns and cities , where there is no armed groups , and closing borders instead , seems better . As light weapons may be getting through the land borders . Aircraft of Russia better fly at high altitude , to avoid manpad . Attacks done instead with artillery . Vehicles can be fitted with cage armour to give some extra protection . But a direct response against country supplying them , will prove most useful . Lethal response to lethal aid .
