Start by shooting the flagpole to get Khabko to go get dressed and prepare to meet with Reznikov. You will need to eliminate all the guards around the main building, including the non-target guards. Then open the main gate to start the prison riot and spread it through the different areas, without causing any fires. Finally, keep Reznikov distracted by shooting near him while he tends to the prison riot. This will cause Khabko to get annoyed and call Reznikov.
