Note to all, flamers and personal attacks will be ignored. If you persist in them, I'll merely report you.

No good in usage for ground support.
No. Not even remotely true. For one thing, the projectiles launched from a railgun don't have to be ferromagnetic, they only have to be conductive. A tungsten slug is diamagnetic, meaning it's as magnetic as a piece of wood. Furthermore, even if it was magnetic, it would not be profoundly affected by earth's magnetic field because it's so pathetically weak. The amount of energy required to create a magnetic field that would profoundly affect a hypervelocity ferromagnetic object is ridiculously high especially considering a magnetic field's strength falls off exponentially the further you are from the source.
