Advanced Combat Environment 3 (ACE3)

ACE3 is the collaborative efforts of the former AGM and CSE teams, along with many of the developers from Arma 2's ACE2 project.

This mod is entirely open-source (we are hosted on GitHub[]), and everyone is free to propose changes or maintain their own, customized version as long as they make their changes open to the public in accordance with the GNU General Public License.

ACE3 is built modularly, thus a team can maintain its own tailored version, excluding a select number of components that they don't like, or which conflict with other addons. Larger components themselves, like the medical system and other core features also include various customization options, allowing mission designers and communities to tweak the overall experience.

Anyone else having the issue in medical where only 1 person can treat someone. If you try and do multiple medical actions one of them gets cancelled. Really sucks when you're stitching someone and it cancels because they remove a Tourniquet

Vladimir, simply take the medical item from the AI and it should convert into proper items once in your inventory. Despite this, the AI are capable of performing medical tasks.

HOWEVER, taking first aid from vehicles results in conversion of items, but the first aid does not disappear. Thus, you get infinite first aid. :(
