Plasma weapons

[Scottyvader]

I have a problem with the power cartridge explanation in that it sounds too much like the plasma warheads listed in the same book, like for instance the fuel rod gun in halo could easily be seen as a form of gravitic gyroc launcher firing plasma warheads and if thats the case why have "energy" weapons that are effectively the same thing?

Thanks guys this was my first forum posting and it was surprizingly productive and I think I will be participating in this forum more often as so far you guys have been awesome.

Thanks!
