Krav Maga or Muay Thai

If your in security then I think Krav should do just fine. The lack of sparring could be a problem....if you’re thinking about fighting the aggressor instead of just neutralizing him or running if you’re outnumber.

I enjoyed Krav Maga, it’s simple and easy to memorise. I stoped going simply because I live in one of the safest and peaceful countries in the world and also because there are other more effective methods for self defense. One the best is simply to run away from the problem, but if I was working as a security I would most definitely joined Krav Maga again (provided that you as a security guard have always with you self defense weapons like a pepper spray or a tactical flashlight).

If you can do both and if you want to try MT and KM then go for it! I also enjoyed MT but I always approach it simply as a fun sport and not as self defense weapon.

To conclude: for neutralizing an attacker most definitely Krav. Just look at those videos on YouTube where Israeli soldiers are demonstrating Krav
