What were the two key features of the Red Army?

The two key features of the Red Army were its political loyalty and the emphasis on political commissars. The Red Army was not only a military force but also a political entity, with commissars ensuring that soldiers adhered to Communist ideology and the goals of the Bolshevik Party. Additionally, the Red Army's organizational structure allowed for rapid mobilization and adaptation, which was crucial during the Russian Civil War and later conflicts. These features contributed to its effectiveness in both maintaining power and engaging in warfare.
