If I had been to design a weaponry paradigm for Terrans, I always felt that it would be cool for them to have (what I'd call) an "iron" or "steel" weaponry system. No energy weapons, those cost too much power. Massive ballistic cannons firing huge HE or AP shells in a straight line (easier to evade than beams, yes). Limited amounts of massive guided torpedoes, launching with a flaming blast from huge dorsal silos or front-mounted tubes. And light, short range, swarming missiles complemented by space machine guns for close-in defense.
Whereas the Zods and Shivans would be the one with beams and lasers. I think that would have made the races feel a bit more alien to each other. As it is, I was always surprised at how similar Terran and Vasudan weaponry is: beams, blobs, missiles, etc. Of course that was very much in the interest of

as it saved time on multiple levels, but still.
