I personally believe that the animations are good in terms of speed, it should take that long to reload a machine gun for balance and realism reasons, but I do think that the reload is too smooth. For instance, in real life, when the player gets the magazine out of the pouch, he will raise it as quickly as possible. This can be balanced by increasing the amount of time for the player to both get the magazine out of the pouch, and load it correctly (it is in the heat of battle after all and there is a sense of urgency, people can fumble about under pressure).
