Of the several specops teams, each with a specific mission profile
and skill-set, I have had the privilege of meeting and working with, I have
a hard time rating one over the other but being a CSAR disciple myself, I lean toward Unit 669, all are superb at their work. If you ever
get the opportunity to take a Krav Maga course taught by one of their instructors
I strongly recommend you take advantage of it, even if you are skilled in other forms.
They have a website you can join to learn more about IDF here.
