The defense secretary wants to cut the Army to pre WWII levels. Guess we don't need rifles or boots on the ground anymore. In WWII the Germans had much superior weapons vs. the allies. We won because we had more people and more weapons, This was played out on the eastern front where Germans were defeated by more soldiers on the Russian side,
It appeared again in the Korean War where we had superior weapons but China flooded the zone with troops. Not to mention Vietnam.
