PLEASE DON'T DOWNVOTE UNLESS YOU READ AT LEAST THE "Additional Information" PART OF THIS POST! I AM ONLY RECCOMENDING ADDING THE TECH UNDER THE ADDITIONAL INFORMATION SECTION TO ARMA 3!
This may still be in the works, but it's just something I noticed.
The soldiers in this game are equipped remarkably similarly to today's soldiers - they have nothing indicating they are 22 years in the future. In 22 years, technologies currently under development in DARPA type labs will be released.
Recently the american military has released prototypes to the equipment soldiers could be wearing in both 2010 and 2020. The progam is called Future Warrior. Barring cost, this is what the Army expects soldiers to look like in the future. Of course, most of this won't happen (exoskeletons, nanomuscles) because it's so expensive.
Some tech the 2010 Future Warrior soldier is equipped with:
-17 inch equivalent HUD in helmet containing interactive maps of the locations of all friendlies, patrol and attack routes, live intel, and other information as added by military leaders.
-Voice controlled computer systems
-Direct communications with air support (video feed, etc)
-Bio-monitoring system monitering core temp, heart rate, skin temp, etc
In addition to this, the 2020 Future Warrior soldier is equipped with
-Nanotech "liquid armor" that turns solid upon impact of bullets, and repairs itself by turning back into liquid after the bullet collision.
-Suit that uses artificial muscles to increase the strength of the soldier, giving 25 to 35 more lifting capactiy.
-Robotic exoskeleton legs allowing soldier to carry 300% more weight with less felt fatigue.
As far as weapons are concerned, "smart" airburst grenade launchers such as today's XM25 should be in wide use among the infantry - http://en.wikipedia.org/wiki/XM25_CDTE#Design
-Laser rangefinders will be built into even the most inexpensive scopes.
At the moment, 2035 is looking like the same exact technology as today but with tweaked names and prototype vehicles that have pretty much exactly the same capabilities.
If you're going to make the game in the future, at least try and make it realistic FOR THE FUTURE. No laser cannons, plasma rifles, but stuff that soldiers already have prototype access to NOW, or stuff that already works 100% today but is prohibitively expensive.
