I can confirm that in 2035 "recycle" is no longer in use!

Well, I tried to do things when diving yesterday at the pool in order to test the theory. What I noticed is that when I try to simulate changing mags underwater (or doing something similar), my concentration level on moving my legs is hugely reduced. I noticed that I moved my legs in a faster irregular manner. I admit that I'm not a professional diver, but changing mags is not an easy thing to do either (especially under water). So, my vote goes down on this.

I think this is considered as unethical and against some world agreements about armies or something like that.

I don't see why you need that. You will have to change your stance according to cover height for example. So how you will have a favorite stance?

Just a correction: this is Hebrew not Arabic.
This could be a steam issue.

In my opinion this suggestions is not suitable for a "realistic simulation". Where should the player be while he is changing his gear? In a place or 'mode' where enemies cannot see him! The video you shown cannot be called "realistic".
However, the firing range may or may not be suitable for the maps of ArmA II. A firing range facility availability means there is an established army base in the area which may not be the case for the maps.
Regarding the vehicles, it is a good idea but I doubt that it can be implemented in the current game, may be we will see this level of complexity in the future ArmA titles.

Oh sorry. I've been out for some time lately. I tried the latest development build (now at Beta). I can confirm that the issue is resolved as I can't reproduce it.
