Outstanding work. I so wish I would have taken a pic of my ruck setup. For the life of me I can't remember the details. Your depiction is very similar, especially the radio mount. but I'm sure I had more storage below for the C's, 35mm camera, C4, and one or two extra house brick batteries and all the other crap you weight yourself down with. Headset position is perfect too. Can't wait to see it painted.
Your grunts mouth made me think of Butthead from Beavis and Butthead. :)
