"Possibly, an Uzi or other small Sub-Machine Gun for Close Battles or Moving Shots."
That phrase fascinates me (among other things in that post). So if the target is moving, the spray and pray method becomes viable? I guess taking your time and leading must be passe'. Oh, and three assault pistols? I'll assume that meant autoloading pistols. But three? Well, if anything, they'd act as defacto body armor. And he's also tossing in three laser light pointers (for meetings and presentations?).
EMDDIESEL, that's another interesting post. Let's see; M240G is basically an FN MAG weighing approx. 25 lbs. You're going to somehow carry 800 rounds of 7.62 ammo (linked!) so we'll add another 55 lbs. And to cap it off, you're going to strap on 11 30 round AR mags for another 20 lbs or so for a whopping 100 lbs with no LBV. And if you do have an LBV, you're actually going to carry more ammo.
