Artillery

[metier9]

I cant quote the reference it was a documentary i saw a long while back.
It said that 80% of casualties where caused by artillery of one nature or another. It could of been about the first world war instead of the second world war, but is this statement correct? Also, does artillery have that much effect in combat mission to co-inside with the statement?

I noticed from random posts here and there from blitz and battlefront forums, that unless there are trenches present people only take mortars (by example) to counter the odd AT gun? Im new so i might of got this wrong as well.
