does anyone know what fighting style is taught in the irish army and taught in there army ranger wing?

Answer 1

obviously the same as in the british or any other modern army
it is a strange question

Answer 2

Are you asking about their (Irish Defence Forces & Ranger Wing) training as per Infantryman, Signaler, Trooper etc..etc..

or about their style of unarmed combat??

You really need to be more specific when asking a question.
