Okay, my general perception of the Halo marines and army is that, Bungie clearly watched James Camerons Aliens and said “we want them”.
As a result the UNSC are almost always portrayed as an elite, professional and well trained force of men and women. They’re a little outclassed at times, but they’re clearly full time soldiers. I can’t really think of an instance where this wasn’t my general impression of them. True, a few freak out under combat stress but this is either because Flood or how serious things are: Scarabs. The equipment and armor they wear is also highly indicative of this. Full body plate, heads up display, heavy man portable weapons, sniper rifles, tanks and other vehicles.
This becomes a problem in the expanded lore where the scope and scale of the Human Covenant War is shown. It lasted 30 years, saw entire planets destroyed and 60% of the human population die. That’s dead. Not injured, cripplied or suffering PTSD. I mean really if you wandered a human city in 2559 it should be like Paris in 1919; millions of ex soldiers crippled, blinded and broken by the horrors of war. Not this “we are the giants” nonsense.
Which doesn’t work for me. It makes sense in Aliens to have a squad of elite troopers confront a small infestation of xenomorphs. But the scenario in Halo is what I’d call a “Total War”. This is a conflict which is an absolute, all or nothing, war of annialation; in this case nothing less than the fate of humanity being at stake.
Given the length of the war and implied rate of attrition, I find it really unlikely that all of the UNSC military would still consist of full time professional soldiers. They surely should have resorted to conscription and drafted anyone of military age. You’d need to massively increase the size of the military. I mean, frankly the Battle of Reach should look more like Stalingrad or Berlin rather than this bizarre situation of evacuating civilians.
Now, theres a few possibilities here which explain this:
Option 1: The UNSC does use conscription. But, due to the sheer size of the UNSC, it has the time to fully train and equip its soldiers. This gives them the appearance of professional soldiers but actually most of these are basically like GI’s from WW2. However, even this analogy feels kind of at odds with how they are portrayed. I don’t look at the UNSC and see WW2 GI’s in space. I’d also point out that 60% figure and the destroyed worlds whereas the US never fought a ground war on its home soil in WW2. The Soviet Union is a better analogy and even they didn’t suffer 60% dead.
Its also worth adding that any sort of Berlin style defense (sending old men and boys out with rocket launchers) would be relatively pointless since the UNSC could always surrender territory and these forces would just get glassed by the Covenant. So, it would only really be Earth that you would get this reaction and there wasn’t a general invasion like Reach.
Option 2: The UNSC does not use conscription, or deems it counter productive and unnecessary. This is basically like saying the United States would have kept its peace time army of a few thousand men during WW2. Given the rate of attrition (60% is a colossal figure people), you couldn’t possibly sustain an army of the required size with just volunteers. So if they aren’t using conscription, it means that most of that 60% figure consisted of civilians that were never put under arms like they should have been.
Personally I always felt that Bungie never got across the sort of desperation and horror that this sort of war would entail. I think they plucked the 60% figure out of thin air without really thinking it through. If the war got THAT intense, then it wouldn’t be this plucky band of brothers with a full arsenal behind them, it should be brutal conflict in which every last man is being hurled into this maelstrom. Things should be that desperate. So I don’t think they used WW2 as an analogy, I think they were too blind sided by the likes of Aliens in which humanity is in a hugely different situation and it isn’t reasonable that all the human military would be at that level. Partly this is also due to Bungie wanting to keep the games relatively cheerful and upbeat; even though things are Enemy at the Gates level bonkers.
I also don’t think 343 has really considered the physical effects of a war that killed 60% of the population. We see worlds like Meridian to be sure, but its really the people and the wounds they carry that should be stressed. There shouldn’t be a single family that didn’t lose a loved one or had somebody horrifically injured. Blinded, burnt, lost limbs, PTSD; the list is endless. The streets should be lined with beggars and broken men and women. Not “oh no, poor me, I have to mine the glass off this planet.”… :I Again, tonally, 343 might just consider that too extreme for the sort of story they want to tell.
