Requires the latest version of CBA A3.

ACRE2 is a full fledged communications suite for Arma 3, allowing realistic radio and voice communications through TeamSpeak 3.

The project is entirely open-source and all contributions are welcome. Core project is licensed under GNU General Public License (GPLv3). Some folders may contain a separate LICENSE file, specifying differently licensed items.


  • Accurate simulations of AN/PRC-343, AN/PRC-77, AN/PRC-148, AN/PRC-117F, AN/PRC-152, SEM 52 SL, SEM 70, BF-888S.
  • Vehicle racks AN/VRC-64, AN/VRC-103, AN/VRC-110, AN/VRC-111, SEM90.
  • Deployable antennas.
  • Real time voice occlusion for world objects, including buildings.
  • Babel language system that allows you to implement virtual languages on other players.
  • Multi-channel audio, allowing people on the radio to be heard locally as well.
  • Radios with external speakers.
  • Possibility to share owned radios with other players.
  • Highly detailed radio signal simulation.
  • Zeus and spectator modes integration.
  • Multiple signal propagation models: Arcade, LOS Single path, LOS Multipath (default) and, experimentally, the Longley-Rice (ITM) model.
  • A highly customizable and documented framework for the creation of radios.
  • A highly customizable and documented framework for implementing different game modes (persistent world, replays, logging, external data storage, external radio control).
  • A highly customizable and documented framework for implementing intercom systems and infantry phones.
  • A highly customizable and documented framework for implementing vehicle racks and their integration into the intercom system.
  • Customizable sound configs that allow traditional patching of sounds played in ACRE via Arma addons.
  • Customizable radio presets, allowing mission makers to define radio presets as well as an API to take advantage of (as an example see the ACRE2 implementation in the TMF).
  • Enhanced and easily configurable vehicle sound occlusion.
  • Ground spike antenna for improved signal quality.
