Russia's reinforcements: Where Putin has found more weapons and troops as Ukraine invasion drags on

Russian President Vladimir Putin has tried to source weapons from North Korea and Iran while hiring mercenaries and fighters from Afghanistan and Syria.

"Russia clearly wasn’t prepared for the nine-month slog that it’s fighting in Ukraine now," Rebekah Koffler, president of Doctrine & Strategy Consulting and a former DIA intelligence officer, told Fox News Digital. "Putin thought that it would be a one- to two-week project, [and] Russian intelligence failed to accurately estimate Zelenskyy's ability to galvanize Western support, Ukrainians’ will to fight, U.S. and Europe’s willingness to provide unprecedented levels of security aid and the Russian forces’ tactical limitations."

Experts previously told Fox News Digital about how "rampant" corruption undermined Russia's military, with oligarchs allegedly pocketing the money instead of investing it in the military over the past thirty years since the Soviet Union collapsed.
