Knowing the 1.2m people strong People's Armed Police Force exists and isn't part of the official defense spending isn't some magic knowledge. China is relatively upfront about the PLA's budget. PAPF not so much. Hence the need to estimate.
It's all available on Wikipedia. Hardly an inside scoop.

Russia I can understand. No Wikipedia page for Nabiullina's financial wizardry. Will be in the future but not right now.
Actually nah.
You should know the Russian spending is much higher because Russia is engaged in a peer war. You know how propaganda works right? At the most basic level if you're in a peer war you're lying about this stuff.
You're not going to believe any official Russian casualty reports are you?
Like I said estimates are spending is double the official numbers.
