This war on rocks article can be a good illustration of some of the Russian military's plight in Ukraine. The Russian military has had to use both conscripts and contract soldiers in order to cut costs. In a full-scale war against NATO, conscripts and contract soldiers could have been sent together. But because the war with Ukraine is a "special military operation," there is no legal way to send these conscripts, resulting in a shortage of Russian ground forces and a reduction in their capabilities.
Typical US bollocks commentary. Of course Russia cannot have the same force structure as the US army. Russia has enemies right on its border. Not like the US which can safely use contract troops on foreign conflicts safe from blowback being an ocean away from the conflict zone. Russia's enemies in Europe alone have a much larger manpower pool than Russia, and a larger economic footprint, there is no way to solve that military economic calculus problem without using conscription.
Conscripts need to be part of the Russian force structure concept from the get go. Not a mere afterthought. Also, because of that, like with all conscript armies even mixed ones, any lack of tactical finesse of individual soldiers needs to be compensated with superior officer training at the operational level. For this Russia has much deeper officer training courses and schools than the US. Their officer pool is much larger. This allows quickly ballooning the army size with conscripts in case of full blown conflict without them running around like headless chickens without proper supervision.
Rosgvardia and OMON are not being used for frontline combat. They are being used to police occupied areas. They are in places like Kherson and Melitopol. Not fighting on the front. They are being used to clear those areas of possible insurgents, saboteurs, and partisans left behind by the Ukrainians.
The Donbass militia is operating in the front lines to clear up their own territory for rather obvious reasons. This gives them more political legitimacy when it comes the time to decide their own political future. And a lot of them probably have longstanding grievances with Ukrainian government forces and are willingly going into the fight. Once the fight moves outside the Donbass area it remains to be seen how things will proceed.
I assume Russia will eventually increase the scope of conscription. They will likely increase the amount of conscripts each year in the future and perhaps even increase conscription time to closer to what it was in Soviet times now that the whole of NATO is a possible enemy in the future. The time when the force structure was focused on fighting insurgents or peacekeeping missions abroad is long gone.
