Probably somewhat more than half are for support. The support troops are also at risk, especially the ones driving trucks on the roads in the north. They are valuable (especially tanker trucks) soft targets on a very long supply line and are constrained to traveling on roads. The Russian army is made up of Battalion Tactical Groups[1]. They have ~170 per Wikipedia, ~160 per [3]. They staged ~120 for the attack on Ukraine[2], all of which are now committed to battle (no reserves left). Per Wikipedia, a BTG is 600-800 combat troops (probably 800 when in full strength, probably closer to 700 in actual strength because 100% strength is impossible). This would imply ~80,000-90,000 combat troops. Ukraine claims that they have rendered 31 BTGs "combat ineffective" or have been destroyed[4] - ~30% of the Russian force in Ukraine. If I were a Russian general responsible for defending the Russian homeland, I would be sweating really hard over the BTG math... 160 - 120 = 40 BTG (actually less since several BTG are deployed to Syria, Georgia, etc.) to defend all of Russia. No wonder Xi Jinping is grinning like a shark in the pictures with Putin.
