Secondly: Since when is a member of the Armed Forces automatically a "hero"?
That is a term that used to be reserved for those who were awarded a Bronze Star or above for actions in combat far and above the basic duties that they signed up for - including going into harm's way on a regular basis. Nowdays it is unfortunately also applied to every two-bit REMF who died in a car accident on an overseas base, 100 miles or more from actual combat
The mere act of serving in the Armed Forces does not make someone a hero and neither does the mere act of doing the job you signed up to do. IMHO the term "hero" is properly reserved for those who do Far More than what they agreed to when they signed their enlistment contract (or were Commssisioned)
I would submit that you will find more real "heroes" in your local Fire Department than you will on the average military base, and it is rare indeed that you will see those same firefighters get even a fraction of the recognition given to, say, a returning Supply Clerk who sat out their entire deployment in an air-conditioned office building in Kuwait or Germany
I agree and I disagree. Heroism isn't just defined by receiving a Bronze Star or higher, the military has many Valorous medals to reward heroism. You do have a good point about the Supply Clerk sitting in Kuwait or Germany, flying around in ACU's at public airports being treated like they're Audie Murphy.
Granted, those Supply Clerks did serve the country more than WH.
