Where's the Valor?

Valor is an incentive most often attributed to military focused societies as it is a quality one gets from exhibiting great courage in battle. 

With the rise of technology one has to wonder where is the Valor today? Our wars haven't stopped but the way we fight has changed. Some people don't even need to be physically present on the battlefield anymore. How can a soldier, who is taught that great deeds on the field of battle brings valor, earn valor when he's placed in a situation where he can't exhibit great courage as he's fighting in-front of a monitor rather than the trenches?

Valor has inspired soldiers for thousands of years but technology seems to have taken it away from them. If valor is no longer attainable for a soldier then what other moral incentive is used to inspire? 

After reading a few books on Alexander The Great, there are plenty of times where valor, or battle recognition, was the sole motivator of the soldiers. After all, the Greeks were military focused. If this is what inspired the soldiers then... what inspires them now?  Is the career soldier more of a job nowadays than anything else? There's definitively still recognition to be found as a soldier but, like most everything else, it changed.
