So, I have had Call of Duty: Advanced Warfare for the Xbox One for a while now. I have prestiged three times already, and working on my fourth prestige (I'm only 4 levels away, oh my gosh!) Now, in the game, you can have custom classes using the Pick 13 system, based on the Pick Ten system from Call of Duty: Black Ops II. You can pick 13 slots which include a primary weapon, secondary weapon (or Combat Knife), Wildcards, Perks, Exo Launchers, Exo Abilities, and Scorestreaks. All weapons have attachments. Well, maybe not all of them. But most of them do have attachments! So, here are some loadouts that I have made over the course of a lot of time...

LOADOUT 1
Primary weapon: KF5 - Genuine (attachments: Quickdraw Grip, Rapid Fire, Advanced Rifling)
Secondary weapon: none (Combat Knife was used)
Perk 1: Lightweight
Perk 2: Peripherals, Fast Hands
Perk 3: Scavenger, Hardline
Exo Ability: none
Exo Launcher: none
Wildcard 1: Primary Gunfighter
Wildcard 2: Perk 2 Greed
Wildcard 3: Perk 3 Greed
Scorestreaks: UAV (modules: Extra Assist Points), Missile Strike (modules: Hellfire Missile, Extra Missile), XS1 Vulcan (modules: Overcharge, Extra Time, Extra Burst)

LOADOUT 2
Primary weapon: Bal-27 - Assaulter (attachments: Red Dot Sight, Quickdraw Grip) 
Secondary weapon: none (Combat Knife was used)
Perk 1: Lightweight
Perk 2: Peripherals
Perk 3: Scavenger, Hardline
Exo Ability: Exo Hover
Exo Launcher: Semtex, Semtex
Wildcard 1: empty
Wildcard 2: empty
Wildcard 3: Perk 3 Greed
Scorestreaks: UAV (modules: Extra Assist Points), Missile Strike (modules: Hellfire Missile, Extra Missile), XS1 Vulcan (modules: Overcharge, Extra Time, Extra Burst)

LOADOUT 3
Primary weapon: SN6 - Money (attachments: ACOG Scope)
Secondary weapon: none (Combat Knife was used)
Perk 1: Lightweight
Perk 2: Peripherals, Fast Hands
Perk 3: Scavenger, Hardline
Exo Ability: none
Exo Launcher: Frag Grenade
Wildcard 1:
Wildcard 2: Perk 2 Greed
Wildcard 3: Perk 3 Greed
Scorestreaks: UAV (modules: Extra Assist Points), Missile Strike (modules: Hellfire Missile, Extra Missile), XS1 Vulcan (modules: Overcharge, Extra Time, Extra Burst)

So, these are some loadouts that I have used, and they work pretty good! I get a kill to death ratio of over 1, usually. If the other team isn't a beast, that is.

For a game guide this is very short. If you make more guides like this in the future, I think you should try and make one that's longer and gives more detail about the whole game and how to beat it. However, I think you did a decent job with this guide.
