Just a couple things that caught my eye.
Combat Monster does not jive well with the patient hunter, wait days for a shot, thing you got going on, neither does the sig: golden bullet in your vic. You Hulk out in a firefight, or from a sniper perch, and when the bad guys are down switch in your golden ammo for some Willy Wonka golden ticket satisfaction and/or advertising.
Spec War guys are more likely to have Flashbacks unless you are absolutely married to Combat Monster and were bounced out of the Mossad for it. Snipers work in pairs and you could have Flashbacks at losing your buddy, and could be why your not in cammies today. Also whoever you worked for will have Records on File for you. That is probably where your contact comes from, doing work as a deniable asset off their books. (Assuming you were going Isreali, Irviing Fisher/Krav Maga, but no lang skill for it so I might be off base there)
Your character is a great distance shot and great up close which is a quandry. Sniper you will want to max infiltration. As infil/exfil is the balance of your job, along with navigation and survival. Up close combat is not a main driver for a sniper. Nothing wrong with being able to tussle but you should have all your sniper skills rocking first (you could have learned the hand to hand first of course but you look kinda like a Isreali Def Force guy and getting that good cracking skulls they would keep you doing that and teaching that before sending you to work a scope). Also you should make a knowledge skill Sniper tactics, knowledge skill of your Spec War Grp, Sniper math (Geometry plus wind/temp variables plus your guns variables equals Gallagher moment) which is a must for LONG up to a mile shots, and maybe some Gunsmithing as shooters love to tinker with their weapons. Watch the Mark Wahlburg movie Shooter and it will cover everything you will want to do in game.
Sorry I ramble a bit. See if anything I said is applicable to what you want and I can go on at length from there. I have gamed with some military guys and they get pasionate about details.
One last point, with your tweaked reaction and hand to hand you may want to switch to more a Commando but watch Shooter first it is a limited but playable character. Its a little easier to play a ghost in Shadowrun but Infil/Exfil will still be really high, athletics, repel, and most are paratroopers. You could get many meat skill sets as a SWAT cop. They do not learn survival, navigation, paratrooping, and have great expertise in the city, criminal organizations, street ett, and understanding of police procedures and communication. Somewhat useful in game.
Sorry I just noticed that you had Armorer, gunsmithing thing covered. You also had the Spec War Grp covered but you didn't specify which one. Which is kinda a big deal but you got points on it.
