Yeah but Taros wasn't a Hive Planet.
Taros was an arid desert planet, not exactly the kind of planet I'd expect to be able to support large human populations. Also consider that Hive planets tend to have been built over several millennia of population growth and urban development, so much so that their buildings sometimes escape the atmosphere.
This would allow for a population far vaster than Malthusian calculations would expect.
My point was that it
wasn't a Hive Planet. It was a Desert/Mining Planet, with a pop of 12 million. Which is pretty damn small (that scaling seems a bit off to me too, but I guess you only need so many miners with 40k tech), but still. One would expect a force at least larger than that of a measly five roman legions.
LordBaal, the thing is, they
weren't concentrated on one spot. It's true that only something like eight of the actual regiments got to fight (one died en rout, the other was forgotten about), and they were only given ten in the first place, but I mean, even so, only a hundred thousand people sent, with that large of a fleet of warships?
The US had more troops than that in Iraq, for
years. If a country with a mere 300 million people or so can manage that in a comparatively far off nation, the Imperium of Man with it's human wave tactics (as in, the fact that it has the population to sustain such) should be able to manage at least that much for a few months. Population of the planet be-damned, it's a mining world with output meant for an important forge world, being attacked by vile xenos. You'd think they'd bother to give a damn. The PDF, goddamn, the governor oughta be able to afford more given the trade with the Tau. Maybe he didn't need to, considering all the work gangs were loyal to him/their bosses (who were, in turn, loyal to Tau coin), but still.
Also I hate the fact that they measured in Hunter Cadres, so they could say 'hundreds' as though each operates completely independently while in full scale warfare. Really, I just hate that the Tau have such a poor organization structure for large-scale military action. Contingents being the only real semi-permanent grouping larger than a Cadre. And they contain, what, 3-6 Cadres? So, maybe 400 Fire Warriors at most, plus vehicles and support staff, maybe a thousand individuals in all at the very most. I know it's designed so that players can create their own fluff, but...goddamnit, guys. Figure it out. Permanent military groupings larger than a hundred people are, in fact, useful.
In case you haven't noticed, I like the Tau(part of the reason is the Orwellian
undertones, to be honest). I don't like everything about them. I also like the Space Marines. I mean, they're half-brainwashed testosterone-poisoned genocidal drama queens, but that makes some excellent storytelling opportunity. ((also honestly why haven't the Tau recovered a few bodies at the least and figured out how to make super-soldiers of their own already damnit they obviously have the tech for it and the naivety/inventiveness to try; Battlesuits are nice but they're also bulky as fuck))
