Modern militaries do not rely on manpower
It is lethality of your force not the number of soldiers or sailors
Actually, I believe moral in our armed forces is at a low ebb so motivation is just not there. As far as not needing manpower, equipment can fail. The more complex the equipment, the more prone to failure. You sound like those in WW2 that said we would win with air power alone and didn't need soldiers. They were proven wrong and saying that manpower is unimportant now is just as wrong. Those who ignore history are prone to repeat it. As far as saying we are the only superpower, that is just silly.
The majority of the troops in WWII were grunts. Needed for manual labor, hauling supplies, digging ditches, peeling potatoes
Modern soldiers are better trained and much better equipped. One soldier is more lethal than ten WWII soldiers
Name a superpower anywhere close to our level
Gee, thank you for maligning WW2 soldiers. Of course our soldiers are better equipped now, but so are foreign soldiers. In fact most terrorists are better equipped than soldiers of the 40's. However, when an EMP takes out your fancy equipment and you are outnumbered 10 to one by those “grunts” you are facing, if you have kept up with your physical training at least you can bend over and kiss your butt goodbye.
Our fancy equipment is tested against HAEMP and must recover within two hours
Most soldiers are not combat soldiers. The majority are in logistics, maintenance and combat support roles......in WWII that meant manual labor
Anyone comparing the number of soldiers needed for a WWII unit to what we need today just doesn't understand modern warfare
Today we can take out a target with an unmanned drone firing a missile within three meters of the target with 100% accuracy
In WWII, we would have needed dozens of heavy bombers to take out the same target
