What kind of artillery are we talking about? I assume shelling an area is anti-infantry, not anti vehicle, and not a ridiculous damage output?

(Incidentally, I was wondering about what the curve on survivability rates would be in say WWI or Vietnam, if the average solider had something like say DR: 5. It wouldn't save them from say, a mortar shell, reduce the threat of things like shrapnel, at least until a medic can arrive)
