The entire Bolshevik leadership of the Red Army, including People's Commissar (defence minister) Nikolai Podvoisky and commander-in-chief Nikolai Krylenko, protested vigorously and eventually resigned. They believed that the Red Army should consist only of dedicated revolutionaries, rely on propaganda and force, and have elected officers. They viewed former imperial officers and generals as potential traitors who should be kept out of the new military, much less put in charge of it. Their views continued to be popular with many Bolsheviks throughout most of the Russian Civil War, and their supporters, including Podvoisky, who became one of Trotsky's deputies, were a constant thorn in Trotsky's side. The discontent with Trotsky's policies of strict discipline, conscription and reliance on carefully supervised non-Communist military experts eventually led to the Military Opposition (Russian: Военная оппозиция), which was active within the Communist Party in late 1918–1919.
