So, I've done research, considered what the GM said about our level of technology, and thought about what my faction's primary research went into, and in the end, figured out what I have, I believe.
My faction is the leader in a few fields, though lagging in others. Specifically, neuroscience, power generation and transfer, and programming/cybernetics. We're a bit behind in aeronautics, space stuff, and subatomic physics.
Our military is relatively small for our population and land mass, but highly trained and well equipped. This is not to say they are unbeatable, but they're tough. The basic infantry soldier, though most personnel specialize, is equipped with the GT-70 'Hauberk' Armored Environment Suit. Additionally, everyone in the military, and most people who can afford it outside the military, have neuro-cybernetic jacks. These go in the base of the skull, around where the spine meets the skull, and are integrated into the brain with self-configuring microbots(not nanobots, these are just a bit smaller than a cell, rather than molecule sized) that make sure nothing is being damaged, everything's connected right, can make new connections, fix minor brain trauma...these will link up to the suit and the soldier's weapon(s), allowing him to have better situational awareness, faster reaction times, and perform his task on the battlefield more effectively.
The Hauberk does not have a clear visor like some modern-day riot gear. Rather, it has numerous micro-cameras on the head, which can feed directly into the wearer's ocular processing area. This allows the head to be as well as or better armored than the rest of the body, while still allowing advanced visual abilities. The suit itself is stronger than conventional body armor, and able to withstand greater impacts without losing integrity due to the combination of rigid and non-rigid protective layers together with advanced composites and seals. The rear of the armor seems a bit too bulky for it's proportions, as it contains the flywheel battery that powers the Hauberk.
This being the basic infantry armor, it is not equipped with heavy duty power supplies, extreme long term operating equipment, or active camouflage. It is, however, often painted or otherwise covered with heat-signature ducking and camouflaging paint or materials. One of the main drawbacks of the Hauberk, however, is that it simply isn't stealthy, even with those.
Okay, I got a bit carried away with that. Point is, everyone in military usually wears a pressurized suit(or at least it's capable of pressurizing), quite good, expensive as all hell, but anyway. Weapons at the infantry level tend to be electro-thermal chemical, mainly because the increased recoil is more easily compensated by wearing a full body suit, and the electric current can be supplied by the suit, meaning only the fuel and projectiles need to be in the magazine. Civilian firearms are usually still solid propellant though.
Once you get to higher calibers, cannons and autocannons and such, ETC are very common, though for some of the weapons mounted on heavier vehicles, similar to tank destroyers(where there isn't a turret per se, but the gun has a limited arc of fire, meaning a larger gun can be fitted to the chassis, etc.) railguns are used. Railguns are very common for artillery pieces and naval ships, though gauss weaponry is being experimented with.
Advanced walkers and mechs make up a portion of the military, but by no means the majority; they cannot replace tanks, but are more useful in urban and rough terrain scenarios. Hovertanks(not as in anti-gravity, it's an aircushion like actual hover-vehicles) are rare, but they do have them for aquatic scenarios and hit and run tactics, as well as high-speed transport when air travel would be impractical.
Classic helicopters are not used. Instead, compound coaxial helicopters are used. Coaxial helicopters have two rotors on top which spin in opposing directions at the same speed, removing the need for a tail rotor, and offering better stability and hovering power. Compound helicopters have one or more horizontally facing rotors, which provide forward thrust and greater speed for a trade-off in stability. Compound coaxial helicopters try to combine this, for better stability and speed than a conventional helicopter. There are different designs used for different missions and purposes, of course, so I won't list them.
Planes are relatively poor. But this is at least partially made up for in the improved reaction times, controls, and ability to scan the surroundings due to cybernetics.
One thing to note; UNNE vehicles almost never have cockpits, windshields, etc. unless they're open-topped or meant for quick deployment/escape. This can be a bit unnerving, and yet gratifying to enemies; your enemy is more easily dehumanized/dedraconized when you can't see their face, but it's still fucking scary to know that that helicopter shouldn't be able to see you but it's turning in your direction and spinning up it's guns.
And done.
