There is quite a difference between an ERA Veteran and those that served 'In Country' during any War. Those who served in country in actual combat are a very different breed of Veterans.
Agreed.
Sometimes, they're a helluva lot braver.
Sometimes, they're just the ones who got picked to go in harms' way.
Sometimes, they're (understandably, oftentimes) a lot crazier than the rest.
Sometimes, they just happened to be in-theatre, and never fired a shot, or even saw one fired, but are still entitled to the campaign ribbon.
Sometimes, they were just careerists looking for a CIB to tuck in their 201 file.
Sometimes, they were just plain guys, doing an ugly and damned dangerous job that they were trained to do.
Sometimes - oftentimes - they're our brightest and finest and most fiercely loyal - and our best warriors from amongst all there was to choose from at the time.
As a group, our combat-veterans - and those in-theater ribbon-holders - are all of these things.
But they were there, as boots on the ground, risking more (and sometimes losing far more) than others did.
That, itself, is enough to set them apart and to accord them a special place of honor in the thoughts of their countrymen.
I'm Army. Regular. E4. 11B20, cross-trained and worked as a 64B20, 64C30 [OJT internship] and 71H20 over the course of my single tour (signed-up for 3, out voluntarily in 2 as part of a

I enlisted and served during wartime but was lucky enough to be sent to West Germany to help stare-down the Rooskies across the wire. Our job was to hold Western Europe long enough for NATO to muster reinforcements to relieve us. In truth, we expected that our asses would be in the English Channel 4-6 weeks after the shooting started - assuming that the rumble remained 'conventional' - but, fortunately, it never came to that.
Although I'm proud to have signed-up to help during wartime - and although I first successfully trained as a ground-pounder - my orders took me into the domain of REMF - outside the war-ops theater no less - which is a lesser status, but I am comforted by the idea that at least I showed-up for the party when my country needed help; however, I always take great care to call myself an '-ERA' (non-combat) veteran to avoid the stigma (amongst my brother and sister veterans) of intentionally claiming to be something that I'm not.
It could very well be that the OP's father either (1) was never properly exposed to that commonly-accepted protocol or (2) is claiming such status now as a byproduct of old-age - rather than trying to puff himself up into something he is not. Could be a perfectly innocent mistake, or a case of old-age and great distance (in time) modestly impairing judgment in the matter. Or, he could be acting like a butthead. At first glance, my money is on a more innocent (albeit mistaken or wrong-headed [in this particular matter]) explanation.
OP... it's my hope that some of this, so far, has been of some help to you, and, of course, your father has our thanks for his service.
