This was another model made for the Army University Press' (AUP) Film Teams' documentary "Understanding Combined Arms Warfare" that's up on Youtube.

If you've seen my 7.7cm FK16 model(s), one of the half-shield clips actually shows this gun as well. It isn't animated, the animators just added an explosion/firing effect to the model in-engine.
This model was super fun to work on - I had no limits on polygons and went kinda nuts. I'd have to retopologize it if I wanted to use it in something else. I enjoyed playing with the curves tool for the first time in a while. I think this model was my favorite of all the models I made for this documentary.
