Marathon
-Ability
--Unlimited Sprint
-Pro Ability
--Get over obsticles faster
---This perk is great for people who like to get around the map fast and try to pick people off. I find that Marathon and Lightweight really go hand and hand with each other. Marathon lets you have unlimited sprint and Lightweight lets you have faster sprint. Marathon is also great for getting out of those tough battle situations that we find our selves in a lot of time.

Sleight of Hand
-Ability
--Faster Reloading
-Pro Ability
--Faster aiming down the sights
---I like to use this perk with really long reloading guns like the Light Machine Guns, Snipers and Shotguns. I do think that this perk is really great for all guns though. It allows you to reload fast and then jump right back into battle.

Scavenger
-Ability
--Restock ammo from dead enemies
-Pro Ability
--Larger Magazines
---I really like to use this perk for all guns. I think that in Modern Warfare 2 you run out of ammo a lot faster than previous CoD games. I like to carry this perk with me at all times. I strongly recommend this perk with Assualt Rifles, Shotguns, and Snipers. The thing that I also find great about this perk is that it resupplies your equipment and grenades. I really like using this for claymores and semtexs. The larger magazines that you unlock with the Scavenger Pro is also amazing for all guns.

Bling
-Ability
--2 Primary Weapon Attachments
-Pro Abilty
--2 Secondary Weapon Attachments
---I like to use this perk to experiment with different combinations of weapon attachments and also to help me unlock weapon attachments. For example, if I wanted to unlock thermal sight and extended magazines, I would put FMJ and ACOG scope on the same weapon. Experiment with this perk and try to find different combinations that fit your play style.

One Man Army
-Ability
--Switch classes in battle
-Pro Abilty
--Switch classes even faster
-I like to use this perk when somebody has air support overhead. I would just pull this out and switch classes to knock the air support out. The only thing I don't like is that it replaces your secondary weapon.
