Though he is an excellent marksman, Tyson has an obvious bias towards knives rather than guns when he needs a weapon. For a multitude of reasons: wanting to remain as quiet as possible, utilising the twenty-one feet rule, and needing to make sure the death sticks to him.
When he needs to use a gun, Tyson favours using handguns: his normal Glock or a Browning ideally. He genuinely hates when a situation calls for a shotgun, but Tyson knows how to use any gun with a reliable aim. He’s nowhere near the kind of shot Sebastian is, but if the Colonel had fallen, it would have been his job as his spotter to take the shot instead.
When it comes to knives, Tyson usually relies on his hunting/combat knives or the various switchblades that he has hidden around his apartment: and London as a whole. Given a choice, Tyson tends to favour a clip point, but he also keeps a few drop and tanto points around.
