Their buying power within Russia is probably 3x that or more, plus because they have an extractive economy a disproportionately high proportion of GDP goes directly to the state, and because they are an oppressive state a disproportionate amount of that goes to the military. Russian defence spending is about 1/12 that of the US, but between having lower grade equipment, conscription and cheaper domestic prices they probably get 2x to 3x bang for their buck, at least on paper. As we can see in Ukraine, in practice much of the bang is over hyped, but it still gives them the brute muscle to do a lot of regional bullying.
