You forgot the "warp-capable fusion missle" for the humans, presumably a fusion missle of superlight-speeds with a very large range, as well as the allmighty wave motion cannon (probably a blue lightning beam), which should be the colony-eraser instead of the nuclear missles.
As for the Jjaro, they probably use the Trith Xem on their dreadnaughts and other major ships, as well as creating event horizons like at the end of Infinity (except these would be temporary), and maybe quantum fluctuation cannons or some techno-babble sounding weapons. I'd imagine the Jjaro should be almost unstoppable (like 5x shields/firepower/etc. of the Pfhor) but all their ships should be large and insanely expensive except their fighters. They should still be able to win if all things except race are equal (like the Auds in real Ares). I think the Jjaro should only appear in a few missions, and in most be "neutral" (attack both Pfhor and player). The dreadnaught should only appear in single player opposing you (or under Durandal's control in the last level).
The event horizons would vary directly (bigger ship, bigger horizon) with the size of the ship, and look like big black circles. They'd simply sit perfectly still doing massive damage to all that crossed them (except obviously the player they belong to), but not dieing until their time limits were up (they should be set so that they can't be collided).
Also, don't forget that particle beams are turreted. If you don't believe me, ask Battle Group 3 - wait, they're dead. Oh well, you get the idea.
As for Battleroids/Juggernauts, I think they should DESTROY ships over a period of time while making firing/screaming sound effects. Play "Post Naval Trauma", or read the terminals on Marathon's Story. Regardless, all weapons that transport troops onto enemy ships should have them make firing/screaming noises and interfere with the controls for a bit. The noises and stuff seem a nice touch of Bungiesqk humor/pseudo-realism.
The plot seems OK, though. The way I see it, Durandal (with Thoth inside him) is galavanting around looking for a Jjaro Dreadnaught. He's going to come back when the Jjaro do (but the humans won't know & the S'pht will) to get one, perhaps peacably, perhaps not.
That corvette model, if I may be so foreward, looks a little like a fighter, as that blue bubble looks like a canopy. Maybe make the back less wide and rounder and make the bubble gray? I just checked the M2 manual...
As for the human/nar/Nebulon ships, we don't know what they look like at all (except the Human Colony ship and Shuttle) and might have to make up (the human ships could use the Ares human ships, they seem similar in my head). The Pfhor design methodology is rather well known, and 2 classes of their ships have been show by Bungie to us in the M2/MI manuals.
The Jjaro appear to construct spindley structures (like the station, which had many booms into nowhere), and thus probably rely on shields far more than armor. I'd be willing to handle the Jjaro ships.
The Nar ships are massive patchwork constructs, quite possibly employing weapons from a variety of sources. They run on coal (really) and thus would be very slow, but according to Bungie very efficient (huge energy supplies). They're probably the only race with shields better than their guns.
Absolutely no clue about the Nebulons. Mostly the Nar and Pfhor beat the crud out of them unmercilessly. They probably don't even have a decent navy anymore. Their advantage (assuming UESG as 1.000) would be like 0.245 or something.
Oh, and coming soon from Darkk and Marathon's Story: what the races look like if you can ever find someone to draw them.
BTW did anyone else here know CFN units are sport utility vehicles with guns? It's apparently true, although very few were supposed to know. It's implied in a secret terminal.

"Strategic warfare" is code for "killing civilians", and it's my calling. Yeah, it's barbaric. War's supposed to be.
