Arma 3 Realism Overhaul, ‘A3RO’ for short, aims to achieve realism in aspects not covered by other modifications as well as improving on existing ones, all the while maintaining the highest possible level of backwards compatibility, featuring native support for CDLC and other Modifications.

A3RO is also available for download on GitHub[github.com].

Core Features

Ammo Overhaul

Every Ammo Type used ingame has been re-evalued, with a new, standardized configuration applied across the board.
Air Friction, Calibre, Hit Values, Audible and Visible Distance ranges, Projectile Lifetime and more.
With ACE loaded, Ballistics Simulation is taken to the next level. Every Ammo Type has received updates to its ACE Config where possible.

Tracers Overhaul

Tracers Ignite and Extinguish just when they would in real life. Every single Ammo Type has been checked for this.
Tracer Size Scaling has also been standardized. You will see the difference of being shot at by 5.45×39 or 12.7×108 as clearly as night and day.

Explosives Overhaul

Underbarrel Grenade Launchers have been rebuilt from the ground up. Different Calibre Launchers have different Grenades available to them.
Increased Lethality, Grenade Selection. Launcher Missile and Rockets, Warheads and Projectiles.
Hand Grenades will be Overhauled in 1.2

Magazines Overhaul

Every Calibre where Tracer Ammo exists now has Magazines with them made available. Depending on the Magazines’ Capacity, this can be just before Reload, every Round or on every 4th Round.
In turn, missing tracerless Magazines have also been created for a consistent experience.
Thus a few hundred new Magazines have been created to fill the gaps throughout the Game.
Over 600 Icons have been created to help differentiate between the various Magazine Variants with their respective Tracers load.
Every Magazine features a Description, aswell as an Abbreviation to be displayed in the UI where required. You will know what you are using.
Every Round, Every empty Magazine, Every Belt Link, Every Pouch. Everything was taken into account to achieve the closest approximation of Magazine Weights yet. Belts. Are. Heavy.

Weapons Overhaul

Every conceivable aspect of Infantry Weapons has been analyzed, researched and adjusted to achieve the most accurate representation possible.
Name, Description, Mass, Rate of Fire, Accuracy, Muzzle Velocity, Barrel Twist and Length, Compatible Calibres and Attachments, Zeroing.
Countless Inconsistencies and incorrect Attachment Slots have been fixed, replaced, and hidden ones added.
Few Settings Remain yet to be touched upon. But they will be, in 1.2

Attachments Overhaul

In the same manner, every type of Weapon Attachment has been reconfigured to represent its real life counterpart.
Name, Mass, Magnification, Descriptions that provide useful Information on Ranging, Zeroing based on Magnification.
There is more work to be done. Attachments will receive a massive Overhaul in 1.2

Weapon UI Overhaul

The Position and Scale of Attachments displayed on any weapon in the Inventory is now accurate.
The ROI is marginal. And yet it was done.

Backpacks Overhaul

With increased burden, existing Backpack capacities would not do. They were too limiting anyway.
All Load Bearing Backpacks have had their capacity increased, and their Weight set to the real value.
Statics Backpacks and some other functional Backpacks have also been modified.
While currently a hasty addition, a proper revision will follow in 1.2

New Content

With everything in place, the stage was set to create derivative content, and so it was.
Civilian Sporting Weapons based on existing Gear, additional Weapon Families, Weapons and Attachments hidden in the gamefiles revealed and re-configured.
Meticulous care was placed on Texture work. You will not find a Semi-Automatic Rifle with a Selective Fire Switch.

Maximum Compatibility

No stone left unturned. A3RO is intended to apply all changes across the entire game. That means: No missing Magazines in Units, no missing Editor Objects, no Errors or Bugs in any Vanilla Scenario.
Where Class Inheritance prevents a full replacement, new classes were created and applied throughout.

Dependencies
Hard Dependencies

The only Mod required to play A3RO is CBA_A3[github.com].
CBA_A3 provides vital functionality and intercompatibility options that allow A3RO to be easily applied onto other Addons.

Soft Dependency System

As of Version 1.1, native compatibility has been achieved with ACE3[github.com], ACEAX[github.com], ACE_Tracers[github.com], Western Sahara CDLC and Real Engine.

ACE 3

Loading ACE3 will apply all A3RO patches onto ACE Calibers, Magazines and Items. In turn, ACE Configuration is applied to all classes edited by A3RO where possible in order to create the most realistic version of Arma 3 yet.

ACEAX

Loading ACEAX will enable A3ROs custom categorization of all Weapons. Other ACEAX for supported Addons can be run alongside to sort content unaffected by A3RO.

ACE_Tracers

Loading ACE_Tracers will apply ACE Tracer Models to all Calibres added by A3RO. Furthermore, ACE_Tracers benefits from A3ROs Tracer Scale Standardization.

Western Sahara CDLC

Loading the Western Sahara CDLC will apply all A3RO adjustments to the DLC content where possible. Derivative Content becomes available.

Real Engine

Loading Real Engine will cause it to be overwritten by A3RO in aspects wherein RE and A3RO clash. The result is a seamless integration of both Mods.

Planned Updates

Full Creator DLC Compatibility

Reaction Forces and Expeditonary Forces Compatibility will come.

Crates Overhaul

Left out of 1.1 due to their low relevance, compatiblity is in order nontheless.

Feature Requests

Community requests like ACE_Tracers and Real Engine Compatibility were just the beginning.
There are many more mods that deserve attention.

Ideas Backlog

For every Feature added in 1.1, two more had to be postponed for later, lest the update would never arrive.
There are many great ideas that simply weren’t a priority. Work will continue. But now it is time for a break.

Credits

While this is a one-man project, I still would like to credit those whose resources I have used to turn this mod into a reality:

The CBA_A3 Team – Whose Shared Classes allow my Magazine and Attachment Changes to work throughout the Armaverse.
The ACE3 Team – For their vast and useful Documentation that made it possible for me to create my own Calibres and so much more.
All Contributors to the Arma Wiki – Without whom I would’ve missed countless useful game trivia that assisted my artistic direction.
