There are three main types of twitches that Tyson has; twitching the first two fingers of his left hand, flexing his right hand, and toying with his dog tags.
He does different one depending on how nervous he is at the time. Twitching the first two fingers of his left hand happens when he is nervous about anything as a general that is what he'll do, the other two happen when his nervousness is more specific.
If he feels threatened when he'll flex his right hand. It is fairly common in soldiers and is often a reflex left over from adjusting ones grip on a gun.
If he doesn't know what to say then he'll toy with his dog tags, either by rolling them through his fingers or straightening them out, depending on how nervous he is.
