Operation Trust (Russian: операция "Трест", tr. Operatsiya "Trest") was a counterintelligence operation of the State Political Directorate (GPU) of the Soviet Union. The operation, which was set up by GPU's predecessor Cheka, ran from 1921 to 1926, set up a fake anti-Bolshevik resistance organization, "Monarchist Union of Central Russia", MUCR (Монархическое объединение Центральной России, МОЦР), in order to help the OGPU identify real monarchists and anti-Bolsheviks. The created front company was called the Moscow Municipal Credit Association. The head of the MUCR was Alexander Yakushev (Александр Александрович Якушев), a former bureaucrat of the Ministry of Communications of Imperial Russia, who after the Russian Revolution joined the Narkomat of External Trade (Наркомат внешней торговли), when the Soviets began to allow the former specialists (called "spetsy", ) to resume the positions of their expertise. This position allowed him to travel abroad and contact Russian emigrants. Yakushev was arrested for his contacts with the exiled White movement. In the same year of his arrest, he was recruited in the Soviet secret police by Artur Artuzov. MUCR kept the monarchist general Alexander Kutepov (Александр Кутепов) from active actions, as he was convinced to wait for the development of internal anti-Bolshevik forces. Kutepov had previously believed in militant action as a solution to the Soviet occupation, and had formed the "combat organization", a militant splinter from the Russian All-Military Union (, Russkiy ObshcheVoinskiy Soyuz) led by General Baron Pyotr Nikolayevich Wrangel. Kutepov also created the Inner Line as a counter-intelligence organization to prevent Bolshevik penetrations. It caused the Cheka some problems but was not overly successful. Among the successes of Trust was the luring of Boris Savinkov and Sidney Reilly into the Soviet Union, where they were captured. The Soviets did not organize Trust from scratch. The White Army had left sleeper agents, and there were also Royalist Russians who did not leave after the Civil War. These people cooperated to the point of having a loose organizational structure. When the OGPU discovered them, they did not liquidate all of them, but manoeuvred into creating a shell organization for their own use. Still another episode of the operation was an "illegal" trip (in fact, monitored by OGPU) of a notable émigré, Vasily Shulgin, into the Soviet Union. After his return he published a book "Three Capitals" with his impressions. In the book he wrote, in part, that contrary to his expectations, Russia was reviving, and
