Even if unplanned you need the jungle boys.

Hey, what about Flak Armor? That shit noms modern small arms for brekkie, and tanks a couple Autogun shots too.

Great read. I would've liked if you had thrown in some Catachan Jungle Fighters, but that's about my only complaint.

This is actually pretty realistic when it comes to both settings.

Just guessing by the end of this either 2 things are going to happen.
1. The Imperium gets it's resources and then exterminatus the planet (which is unlikely since that would be wasting useful resources
2. The Imperium gets it's resources and leaves after killing a large amount of Xeno's while letting other Imperials know about a death world the mechanicus can terraform.
Either way the Imperium is getting it's resources and lots of Xeno's are going to die.

In fealty to the God-Emperor (our Undying Lord), and by the grace of the Golden Throne, I declare exterminatus upon the world of Pandora.

FFFFFFFFFFFFFUCKING FAGGOT TAU

Love me some xenos purging. Though if I might add, you might've underestimated the sheer durability of a Spess Marehn. From the book, "Salamander" we have this lovely quote; “Other more minor injuries — severed hands, gouged eyes, punctured lungs — appeared more frequently.”

Suffer not the Zeno scum

I'm sure the Na'vi would embrace the Tau Empire. Until they realized (probably pretty quickly, they're not stupid) that they are just being used as cannon fodder for an empire they have no real rights or voice in and that takes all the fruits of their labors while executing or sterilizing dissenters. Kinda like the Imperium except the Imperium does such things only when their situation forces them to in order to survive. For the Tau, it is the first, go-to choice.

FEAR THE EMPEROR'S WRATH! BURN IN HOLY FIRE! NOMERCYNORESPITERAAAAAAAAAGH!

Suffer not the Xenos to live.

So far, this story is very interesting. 7/10 overall. There's some minor things you could do to improve story flow, but that stuff can only be learned with experience; you're doing very well as it is.

My only real criticism is twofold;

1) You break character sometimes when writing from the Na'vi perspective-they wouldn't even know terms like "infantry", "specialist", or "area of effect". It's a minor thing, but it breaks immersion when it pops up.

2) There are several occasions where the story could be improved by even application of hard science. For example, you describe a Na'vi being tossed through the air after getting hit by several hellgun shots, which is pretty close to accurate (having that much thermal energy transferred into your body that quickly would indeed create a miniature explosion with a concussive effect). However, when Tsu'Tey is grazed by a few hellgun shots shortly afterwards, the only thing you say about it is "a burning sensation". With proper application of HS, Tsu'Tey would have stumbled hard, maybe even fallen, and only after the initial physical shock would he have felt the burning.
