Russia's military "weaknesses are being revealed" in Ukraine, says former commander of U.S. forces in Europe

The Russian Armed Forces are considered the fifth-largest military in the world but retired Lieutenant General Ben Hodges, the former commanding general of U.S. Army forces in Europe, said that Russia's invasion of Ukraine has exposed its military shortcomings. 

"The weaknesses are being revealed in terms of logistics, terrible maintenance, the fact that they don't have sergeants like we do that can enforce discipline. That's where we're seeing the difference," he told "CBS Mornings." 

Another thing Hodges said Putin underestimated was that the Ukrainian people were going to fight back.
