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 get these strange artillery sound effects and green lines coming from destroyed tanks from CUP? Without ACE it works just fine.

Also when using Ace in the vanilla game, that one mission where you have to evade artillery and escape from the island is really messed up, the artillery gets this really strange, almost alien like sound effect.
It's almost like ace is shifting sound effects arround for no reason.

Judging by the comments here it's a minor complaint, but still it anoys the crap out of me.

I've some trouble with the medical stuff of ace. Even though, I'm hit and the avatar is moarning, I can't see any bodypart highlighted as injured in the medical menu. This not only happens for me, my friends have the same and inspecting each others avatars also yields no results other than everything is fine.

Could someone point me to what might be going wrong here?
