Is there a perk like uav jammer in mw2?

Yes there are in fact two. The best one is called Cold-Blooded and it is so much better than UAV jammer. It doesn't just protect you from UAV's but it also protects you from Sentry Guns, Predator Missiles, Thermal Scope, Helicopters and any Remote controlled Killstreak reward.

It is amazingly brilliant and there is also Cold-Blooded Pro which does the same but also prevents a red name coming up when someone looks at you. The not so good one is called Scrambler which makes the enemies radar go fuzzy when they come near you. It's not always very useful because it tells the enemy that your nearby and they will go looking for you.

In MW2 I highly recommend using Cold Blooded Pro as it is the most brilliant perk ever. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
