Best MW2 stealth class

Here is the best stealth class and tips for being stealthy.
Primary: UMP .45 silenced
Secondary: M93 raffica silenced
Equipment: Claymore
Special grenade: Stun grenade
Perk 1: Marathon/Pro
Perk 2: Cold Blooded/Pro
Perk 3: Ninja/Pro
Death Streak: Last Stand

TIPS:

• Check corners with sight up
• Keep crosshairs up at all times-staring at ground is a good way to get sniped
• Always keep an eye on windows and rooftops
• Try to slip into buildings so people cant follow you so easily
• Stick to the edges of the map- while they fight it out in the middle you can outflank your enemies
• Try to avoid your teammates- if they don't have your perks they will make stealth impossible
• Use you knife as much as possible-its quick, a one knife kill, and silenced, the perfect stealth weapon
