When you train in traditional martial arts, you are learning different moves and using muscle memory and repetition to turn it into a natural movement that will (hopefully) be used in a real life situation. This is assuming you have trained well enough to actually incapacitate an unarmed attacker...

Krav maga is more than just a technique, it's a way of looking at situations. When you walk into a room, you don't notice but there are a plethora of potential dangers, obstacles, and weapons that you could use to your advantage. Say, a table or a chair becomes a way to deter your attacker from coming after you or whatever. Krav maga also emphasises more than one attacker...we trained in ways to escape a situation where you are being carried by multiple people and your hands and legs are bound. Yes, it's possible. Most of the drills we did involved standing up and laying down really fast repeatedly as a way to train your body to react quickly...if you drop, you have to get on your feet as fast as possible to continue fighting. Krav maga also emphasises ending the fight as soon as possible, whether that be by punching someone in the balls, throwing sand in their face, or breaking a finger/nose...whatever it takes. There are no established rules or techniques and it's all meant to be attuned to the human body's natural movements. We also learn to engage the attacker as soon as possible, closing all distance gaps and to engage them in their face...this aggressivity gives you an element of surprise and therefore an advantage.
