Perk 1:
Land Mine x2 - Two pressure activated mines. (Like from WaW)
Claymore x2 - Two trip activated explosives. (These work a bit different. You first set down the explosive, and then press the trigger again to put down the stick. There will be a wire from the explosive to the stick, and it will explode if an enemy touches the wire. If you try to set the stick more than 4 feet away, it won't allow you to.)

Sleight of Hand - Quick reloading and movements. (Faster knifing and grenade throwing, too.)
Tactician - Two weapon attachments. (RDS/ACOG, Bipod/Grip non-compatible)
