an ion laser beam could be a weapon.an ion is a positivly charged atom with 1 (or more) positive protons.an ion laser beam takes positive particals and STRONLY high density packs the in to a beam.to destroy it aims at one cirtin area blasts it with positive particals at a velocity of almost the speed of light then HEATS it up and ZAPS it.
the only thing that I think can stop a I.L.B is a powerful negetive magnt
an anion could be a beam to.it is negetive(no proton only electron
