It is a 20 minute video, but it also does a good job of showing the differences with respect to the individual soldiers and their training. For example, Russia's conscripts are only required to serve 1 year, while their "contractual" soldiers are required to serve more like 3 years. The narrator also compares equipment differences and even platoon sized armored personnel carriers with the Russian BMP platoon only have 3 vehicles compared to the U.S.'s 4 per platoon.
