[Ground vehicle] Reload animation

[Robin_Hood]

I was looking at the Roland ADS in the model viewer, and noticed there is a reload animation for each barrel (arg 83 and 81 or 84), but it doesn't seem to be used in-game. Does anyone know if it is possible to use this kind of argument, and how ? A quick search through the vehicles .lua did not reveal anything.

 

Or maybe it is not possible and the person who animated the Roland ADS got a little to excited.
