I expect Russian ground troops to be doing mainly base security, and maybe recon patrols. Syrian government base security stinks - they keep on getting overrun. I don't expect that ordinary Russians will be thrilled about a country that is unlikely to become part of the Russian empire generating thousands of Russian body bags. Putin does need to win elections.
50% of Russia’s budget is derived from oil revenue. World is in and economic depression. Price is $50/$60 below what it needs to be in order for the Russian budget to balance.
As such, Russia is getting ready to shake up the oil industry in the ME. That’s why he’s there.
Every notice that Putin didn’t need to hit Syria with cruise missiles? 900 miles, from the Caspian Sea, right?
They may be able to hit Riyahd from there.
