Nika, take a look at my profile. I'm Israeli.
I served 4 years in the military and went through the 02 Tironut (for the rest of the forum: the simplest bootcamp, the one for non-field soldiers), in which we had some Krav Maga lessons (as I said, nothing extensive, nothing that actually helps in practice). Maybe things were different for him, I really don't know his story in particular.
In any case -- this is becoming really off-topic
He's always been a fierce player. That's his edge over other players.
He's full of talent, but his mental strength and toughness are really the things that could take him to the next level.
