Over the last two months, Russia has likely started forming up major new formations to add depth to its ground forces. These include the 25th Combined Arms Army.
Since its invasion of Ukraine, Russia has mainly deployed mobilised reservists to back-fill established formations, or as part of territorial defence infantry regiments. It has rarely established new, all-arms organisations such as combined arms armies which are designed to be a self-sufficient force. An exception to this was the 3rd Army Corps created in summer 2022, which has generally performed poorly.
Russia will likely deploy any new formation as a reserve force in Ukraine. However, in the longer term, Russia aspires to strengthen its forces facing NATO. Without a major new wave of mandatory mobilisation, Russia is unlikely to find enough new troops to resource even one new army.
