Luke has been learning aikido for nearly 5 years now - he shows us loads of different ways to beat up someone who's going to get you.
Thomas knows all about the different guns the S.A.S. use. He's got some secret S.A.S. books that show you how to take them to bits & how to sniper someone from over 5 miles away. He's actually seen a real gun once (not on the telly) in london last year with his uncle.
Steven's granddad was an S.A.S. doctor & he knows all about different bloods that you have to put into someone that's been shot or exploded
