Hi,
it´s very interesting what you have wrote. The unit animation sometimes don´t looks like realistic as you describing. Without any doubts you are right. Some of them are not so realistic as you´d expect but we´re concentrating our effort to another new projects. Redoing these animations would take enough time. What makes Arma 3 realistic warfare game is whole infantry gameplay, strong combat experience and complex features at control all units. There are some discrepancies (i.e. some animations as you said) but Arma 3 is very complex game.

Thank you for you suggestion. We can focus on it in future.

Redoing these animations would take enough time.

excuse me, as seems to me you are wrong. I may be poorly explained. I think you need to do is to create only one animation and replace in the scripts the name old animation for new name. And it is all!

Now (v1.66) all deployment actions have the one bad animation. This is animation of movement the hands of the void, when the character is in full erect position. But any deployment should be on the ground surface! Why soldiers may not even crouch to the ground surface!? Also Deployment should spend some time.

And most importantly! We are should understand, that it is necessary for the gameplay itself, but not only visual decorate game. When I see that a soldier sets static weapons for 2 seconds, it makes me not love Arm3 fully. In the real life, such things have to spend much more time.

I venture to remind: that for this purpose, you can make one animation (for all deployment actions) that will be longer and more realistic.
