Refitting Soviet-era warships, fielding new aircraft and tanks and seeking new overseas bases, the Russian military — which now has troops on alert amidst a crisis in Ukraine — is more potent than the force that briefly fought Georgia six years ago.

Moscow is seriously investing in building its clout. Since 2008, it has raised military spending by almost a third and drastically reformed both the armed forces and defense industry to tackle post-Cold War decay.

But Russian forces remain much weaker than at their Soviet peak and face huge problems ranging from corruption to a long-term shortage of recruits, not to mention the risk of insurgency if they set foot in Ukraine.
