It varies depending on your skill in Halo, or what sensitivity you're used to. I preferably use 8 which is also my standard speed for everything save snipers(2 sensitivity). In swat I generally don't even zoom in, so I personally recommend going somewhere around at least 6, but again it just depends on you.
In swat, you have to be able to react quickly. Use a higher sensitivity than you normaly do for regular matchmaking excluding swat. if you use 3 on a normal basis i would reccomend 7 or 6 i usualy use 5 or 6 but just go with whats comfortable.
10=best at swat, don't listen to these noobs. Work your way slowly until you feel comfortable at 10. Then become an elite.
Silent is probably right, but at the same time, I play at 1, and hey, Im a 38 in swat. You need to gradually go up as he said, but you can just stop at 8 or 9, if you find that preferable. Also, yeah, go with the elite, they are harder to headshot from behind.
First off, just because we don't use 10 sensitivity doesn't make us noobs. You can compete with any sensitivity. Second, and less confrontational, I hate everyone using Elites just in swat. Stick with one avatar and leave it at that. That's more of a personal issue. Not really on topic. People are gonna tell you higher is better. It may be but no matter what anyone says, your gonna end up using what feels comfortable. Beyond that, using a specific sensitivity isn't going to make you drastically better at SWAT. Only playing will you ever get better.
There is absolutely no such thing as "The right sensitivity for swat". You should just stick to what you normally play on. I use 2 sensitivity on SWAT and I'm doing fine. In fact, you can use 2 sensitivity to do pretty much what someone who plays on 10 sensitivity. You just have to be used to using it.
*Locked* There is not one sensitivity that can be considered the best for swat and thus no need for a topic asking what it is.
