I trow few grenades in my life and it is not much... It is like u trow rock.If u r smart,u will not try to look did u trow it good. In Serbian army 2 types grenades r used,one is so called "offensive" with smaller explosive charges and plastic body,and it does not had so big kill radius.Second is defensive,with stronger charge and full metal body,and not only pellets,but body fragment can kill to distances at 100 m away. U can knock soft skinned venchiles with grenade,but for something like that u must be seriusly close and not likely to heapen. Eaven for house clearing we prefered to use rocket launchers,and some heawyer artilery then to come close and use hand grenades.
