Awesome. As for costs... Hm...

Depending on how much ammo, anywhere from $10,000 to 13-14, but most of that is in ammunition values. A lot of that stuff isn't worth a whole lot, apart from the extra radio. The flamethrower and missile launcher will depend on quality and who they're sold to. The AK ammo is also pretty worthless, since most US made guns use 5.56 rather than the significantly larger 7.62, and the shotgun shells... Depends. If it's 20 gauge, that's a lot more than 12.
