Calradia is in an utter state of total war; I'd be surprised if veterans live long enough to be particularly distinguished from their fellow soldiers unless they get transferred to another unit.
In other words, a veteran doppelsoldner who participated in the storming of Ellis is likely to get the same pay and equipment as a "fresh" (I say that loosely, seeing as all doppelsoldner are meant to be veterans) who got elevated to that position a day earlier.
After all, they have the same chances of survival, effectively, with perhaps a difference of 1%?
Doppelsoldner should be lucky he got a pay raise and a big sword. Could be worse, after all. Also illustrates how human life is worthless in Calradia seeing as you can't treasure a veteran-veteran-veteran unit (with 10 powerstrike and 1000 two-handed, I guess) and keeps them all faceless. I suppose.
