They were mostly wounded while killing, trying to kill, or assissting in killing other people (you know... combat).
It is kind of a moot point discussing who the 'good guys' are in a war. However usually it is soldiers on both sides. A soldiers saving grace may be, that they are acting under orders and have limited choice in the matter.
However for the same reason I do not see a point why they should have a priviliged status.
All things conssidered they rank pretty low on my sympathy list.
Certainly much lower than a wounded cop for example, who was fighting actual criminals and certainly lower than people who were simply the victim of an accident or violence.
