Let's talk armor. Specifically, how armor looks in this setting, with absolutely no change whatsoever to the ruleset.
So armor technology's come a long way since the days of slapping on a neometal plate
vest and calling it a day. Now, in this day of modularity, the truly modern soldier requires the ability to modify their protection to both fit a varying number of sizes, but also better fit for the various missions they must go on. Therefore, what is known as "body armor" is actually a collection of smaller plates attached together in a vest-like whole.
At it's most basic, the one thing all armors share is the chest plate. Chest, shoulder straps, under arm, and back. Standard combat armor adds abdomen plates, usually stomach, sides, and normally an overlapping spine-like back. Particularly heavy armor usually adds upper arm and thigh plates.
What shape this armor takes both depends on the person wearing it (modularity, after all), and the country of origin (because being the exact same design with a few slight differences would be boring).
As an example, the UAO, due to their almost fanatical obsession with the human body, tend to style their armor
in a more curved, musculature-like form, which tends to go well with the ultra long hair that they like to stuff into their well-defined helmets.
The NAS, on the other hand, tends to take a more rugged, sturdy look. Often times the joke goes that NAS troops don't build body armor, they just rip off bits from their battle tanks and wear that. Which isn't far from the truth, since while other nations use a special lightweight neosteel mixture, NAS uses similar alloys that they use in their ground vehicle plating. Basically they are like Halo Reach Army troopers
with more exaggerated shoulder straps, Spartan
-like chestplate, and a more rounded helmet.
And before you ask, yes
women get a choice between a more practical look and breast plates. Ironically, even though breast plates are remarkably more common than you would think (cause I sez so), most "sexy" artwork in this setting usually drops the chest plate altogether for a more corset-y version of the abdomen plating (with plenty of chest belts).
