Yea, Because they use the real Krav Maga not the crap the they try to pass off as Krav Maga here in the states mix Tae Bo & kick boxing meets Jenny Craig. Krav Maga the real Krav Maga is like night & day apple & oranges big different Krav Maga here in the U.S.A. is made for the mass self defense for over weight people or people that of bored of go to the gym to work out to lose weight Krav Maga is CQC at it's dirtiest using you're environment walls chairs any as a weapon and so on. There are no boxing moves like the Jab no high kicking, it's knees, elbows,head butts down and dirty fighting Krav Maga was made for urban combat & CQC not to lose weight & kick boxing class like Krav Maga here in the states it's a joke. The Israeli's I have talk to LOL about Krav Maga that is taught here.
Krav Maga is what the Israeli air marshalls have been using for years. It's worked for them so far.
