In this video journalist Julia Ioffe said that in a "state-sponsored documentary" that aired on "Channel 1", supposedly "the main Kremlin TV channel", Russian president Putin said that he gave the order to send the so-called "little green men" into Crimea. She says that the documentary is called "The Road Home to the Motherland". I've searched for this title but haven't found anything official about this documentary. I found an article on "The Telegraph" titled:

Putin reveals the moment he gave the secret order for Russia's annexation of Crimea

According to the article the documentary is called "Crimea: The Road to the Motherland" and was supposed to be shown on the Rossiya-1 channel. I haven't been able to get any information on this documentary, but I found a teaser on Youtube uploaded in 8 March 2015.
