Portable Autocannon

Alright, here is this guy I've been working on. I had this part of an autocannon without a barrel, and then I thought of making the barrel shorter, and then having him hold and fire it. I realized that that wouldn't work very well, so I strapped it to his back

And then I greenstuffed a rope/cord-ish thing to make it look slightly more realistic

Now all I need to do is to add an arm holding the barrel, and another doing something else, and then have another Guardsman with the tripod, maybe, and ammunition. I will post those pics when I have it done.
