Vasudan Military Doctrine:
It seems to me that the Vasudan military is sort of vulcan in their doctrine. The needs of the many, outwiegh the needs of the few. What this translates into is the idea that what's important is the Vasudan war effort as a whole, and not the individual soldier.
As a result, we have Vasudan Destroyers, Cruisers and even Freighters which are all superior to their Terran equivelants with better armor and weapons. But then they have cheap fighters, with little armour (and later little shields). Whereas the Terrans use decent ships (less armoured and gunned), but better fighters. Because, to the Terrans the measure of worth on an individual is higher, whereas the Vasudans are more willing to sacrifice thier lives for the greater good (ie Kamikaze attacks).
The crux of the Vasudan philosophy boils down to their escape pods which are designed to carry information, not Vasudans, to safety.
As for the Anubis, I think that it many ways the Vasudans can be compared to WW2-era japanese. The Anubis, likewise as a weak yet potent fighter can be compared to some versions of the Zero or some other fighter which had paper thin armor but a big honking 30mm cannon which could blow apart any other fighter in the sky.
One asks "how can a fighter be deadly yet cheap?". It's simple, the Anubis is built is such large numbers that it is cheap. It's like buying in Bulk, the more you buy, the cheaper it is. It's also why something like the Erinyes or the Ares is an expensive craft in the GTVA, not only is it expensive in the first place, but not many of them are built so its doubly expensive. The Anubis is just the opposite. Its fairly cheap, but build a lot of them and then its really cheap.
