Second in Command (2006) on Netflix

Plot summary

Moldavia has a newly elected president, Yuri Amirev, who wants the country run as a democracy, and the United States installed the government he now leads. Communist insurgents under Anton Tavarov riot at the presidential palace, loyal to Alexei Kirilov, the former dictator. Sam Keenan, a decorated Navy commander, reaches the U.S. Embassy in the capital as security attaché, and Ambassador George Norland names him deputy ambassador. When palace guards fire without Amirev's authorization, the insurgents storm the building. Keenan brings Amirev back to the embassy, where Tavarov's army gathers at the gates.
