I want to learn Krav Maga which is a self-defence and fighting style used by Israel Defense Forces.
I've never heard of that, what can you tell me about it?
It's a combination of boxing, wrestling, judo, karate, fight training.
Interesting, what would you use it for, self defense or exercise?
It is used for real-world situations where the IDF needs to maintain peace or immobilize hostiles.
So do other military units besides Israel use it as well?
Not to my knowledge. Krav Maga has a philosophy that emphasizes aggression as well as defensive and offensive maneuvers.
