Obviously, the vertically positioned has fins but lacks a rocket motor (suggesting it may be a sub-munition, or an airlaunched rocket).... the horizontally positioned one is the forward part of a partially shown, partially obscured munition > we can't see the rear end to determine rocket or bomb.
I'm not sure vertical item is the same as horizontal item; first may be submunition for a larger caliber rocket, latter may be smaller caliber rocket.
