I thought America spends $500 billion dollars on its military far exceeding whatever Russia spends on its own military, but taking a look at the military statistics below the strength gap between the US and Russia is not as wide as the difference in military budgets between these two nations. Therefore I wonder what America does with a whooping $500 billion budget.
From the statistics below, America has a bigger population than Russia so it translates to America having an advantage over Russia in man power. Russia appears to be more powerful on land, while the US reigns supreme on Air and on sea. Maybe Russia's surplus land based weapons will be enough to answer America's Air and sea superiority.
