Well, I said 'their' own ship. Sorry, it is a group thing. And I'm afraid that energy weapon is very high end. Thing is, energy weapons in this setting are quite large, more akin to cannons. For instance the smallest energy weapon is the Gungnir Laser Destroyer, which is roughly the size of an M60. I'm thinking more of a grimy kind of Sci-fi, more industrial, less 'Ipod.' As for railguns, they aren't man-portable. In fact, Browning M2s are still in use! Sometimes, you can't beat the classics.
