A couple of quick comments and stuff for people as I look over your characters…
DanMcS - Left Shield looks good. I am not 100% what I want to do about shields and firearms. There is a reason there are not used much these days. BUT for now will leave it as is. The chances to Feats etc for his Occupation and Bodyguard look ok and reasonable. There are 'firearm' cannon like weapons in the Dragonstar worlds, and they are common.
Mithran - if you would rather carry a Glock 17, it is probably one you purchased yourself, and carry which is fine. Grenades will be issued to you per requests. They don't think you need carry lots around, but 2-3 Frag and Smoke are easily available.
ferretguy - instead of the M60 I think I am going to use the M249 SAW light machine gun. It will use most of the stats of the M60 light machine gun, except that it is Large (instead of Huge). It still uses linked ammo, to get away without having a "feeder" there are the 50-round belt-feed "boxes" or the drum-magazines (but I am not sure how many those hold, but I would guess 50 also). Anyway a picture of it can be found here…

Captain Tagon - I am not sure they will issue you a Barrett Light Fifty, only because you are going to be traveling light and it weighs 36 pounds by its lone some. The HK PSG1 7.76mm sniper rifle might be a bit easier as it is only 16lbs and is a large weapon (you don't need to tri-pond out to use it). Just a thought, if your heart is set on the Barrett it will be issued to you.
To All - some basic equipment that will be issued to all…
Combat Fatigues, Snow-Camo pattern (+2 to Hide in snow environments) 3lbs
Thermal Jacket, light weight and snow-camo pattern 2lbs
Mesh Vest (adds +2 to strength for encumbrance) 7 lbs
Military grade Walkie-Talkie with throat mic 1 lb
Flash Goggles 2 lbs
MRE (meals-ready-to-eat) three days 3 lbs
Weapons that are generally issued…
Berretta 92F Pistol 3lbs; with shoulder holster
HK MP5 SMG, with custom internal sound/flash suppressor 7 lbs; with shoulder strap
Illuminator and/or Laser Sights are optional add-ons (+1/2 lb each for each weapon)
masterwork Combat Knife 1lb
Frag Grenades 1lb
Smoke Grenades 2lbs
Some other equipment that they "suggest" at least some of you carry…
Night Vision Goggles 3lbs
Detonators for specifically requested explosives (like C/4)
First Aid Kit (only a -2 to use to Stabilize dying character) 3lbs
Medical and/or Surgery Kit (each 5 lbs)
Others equipment is available, depending on what your character wants, like I said above, the M249 SAW light machine gun and the HK PSG1 7.76mm sniper rifle are available for those specially trained for them.
Basically the military will provide you with a lot of stuff…
BTW - you are all part of SGC -1. There is a SGC -2 that will also be coming on the mission. They will be setting up a base camp not far from the gate, where they will have some extra supplies, ammo, food, etc so that you are not expected to carry everything. They will mostly try and stay hidden, but will serve as a fall back place not far from the gate if things go bad…
