i've been in the German Army for quite some time and have ample experience with the correct handling of the G36.
I've seen your fast reload animation and i like how it actually represents a taught reloading procedure in the German Army.
The issue i see with it is that it's actually the reloading procedure for when having ample of time and just changing a magazine that has a few cartrdiges left in it.
So the actual fast reload we have in Sandstorm for the G36 should be the normal reload animation.
The currently normal reload animation for the G36 in sandstorm should be the fast reload(It would be cool to tweak it, making it faster, or changing it so that the pointing finger of the right hand pushes the magazine catch away so that the magazine falls out of the rifle by manipulating the rifle with that one mentioned finger).
