Krav Maga
http://en.wikipedia.org/wiki/Krav_Maga
Commando Krav Maga - the guy claims a lot of thing, former special forces in Israel blah blah blah, can make you an instructor in 3 days, IDF rubbished his claims so now he recanted a lot of his former resume
Kapap is basically unarmed combat that was taught to the IDF in their early days before they switch to KM in 2000.
Each has its own merits but the techniques taught here are more for self defense and then transit to offense since the syllabus is for civillian (vs. military, law enforcement) but one good thing abt the instructor for krav maga
is that he teach everything and don't hold back.

Two of my friends also went down with me, one is not so committed, while one straight away sign up for 10 lessons after lesson 1 despite his arms being bruised
