Yes, I believe that the Order and DA were always engaged in something war-like (whether you separate Voldemort's first war from that of the final books of the series, or not). The final battle (DH) is indeed quite revealing. The HEAT of war. Death all around. Pain. Senseless killing. And for what? What did the Death Eaters expect to gain? Just following orders? So this is war. Or is it?
Who are the warriors? Voldemort? B. Lestrange? McGonagal? Weasely family? Hagrid? Lupin? Tonks? Kingsley? Snape? (well . . . ) What about Harry? Ron? Hermione? Luna? Neville? Dobby? Griphook? Olivander? Aw, come on. Certainly Mad Eye!?
So are we any closer? What makes a warrior great? War is really not my bag. Reason: Kid games and sports like "cops and robbers", electonic war games, etc. Even Quidditch, if you know what I mean. It's "fun" to win. War's different. Warriors, I think, are different. They do what they must. Centered. Protective/Defensive. Pursuing peace. Not mercenaries.
Yoda seemed to know a thing or two, eh?
We seem to be no closer to answering the question of what makes a warrior great. I like your point that warriors are different than the wars they actually fight in that they do what they must. Harry and his friends did what they felt they needed to do during war time - it was a defensive tactic, and no, they most assuredly are not mercenaries.
The same cannot be said of the Death Eaters and their fearful leader, can it? Is Voldemort a warrior? I think of him more as a dictator, personally, but then again, it could easily be argued that a dictator is also a warrior - which seems to get us nowhere.
Dictionary.com gives us the follwing definition(s) of a warrior:
QUOTE
1.a person engaged or experienced in warfare; soldier. 2.a person who shows or has shown great vigor, courage, or aggressiveness, as in politics or athletics.
Well, if we were to take this definition into consideration, then, yes, even the villains in Rowling's world can be considered warriors. Bella and her fellow Death Eaters were certainly engaged and/or experienced in warfare, and they were certainly soldiers in Voldemort's army. And it definitely takes a certain amount of great courage to be a warrior - no matter the direction one wishes to take that courage (in Voldemort's case, he's courageous in his quest for power and his aggressiveness in getting what he wants - although he clearly lacks courage in other, and ultimately more important matters.)

And even Ollivander says, "He-Who-Must-Not-Be-Named did great things -- terrible yes, but great."
So, based on the definitions we have for a warrior - would we consider Voldemort to be a great warrior? - Perhaps like Achilles, he had his flaw, his weakness - but overall, he was great in his own way.
