Grim - Depending on what era you were looking at (speaking of Verlinden kits), there are two kits that if you purchased, you'd be good. They are the Iraq/ Afghan SF conversion kit #2473, and Modern US Iraq/ Afghan kit #2177. Granted, these are for American figures.
As far as the weapons go ... IMO, I think that BLAST models M4/ AR15 family kit is the way to go. There are a few sets/ kits out there that do offer decent M4 weapons, like AFV's CROW kit #35157 (I think that it has 2-3 rifles in it.)
I'm still looking for a decently priced kit that will offer a nice shotgun (short stock), an M240B, a combat SAW (short barrel/ short stock), and maybe a slew of M4 variants .... but then again, I've got better chances of winning the lottery!
