“He is best that is trained in the severest school”
-Thucydides
New Zealand is a small country and yet their SAS regiment has to maintain the capabilities and lethality of their larger commonwealth SAS peers in Australia and Britain, to the point of seamless integration on joint operations. For this reason, I have been greatly inspired by the NZSAS, specifically their selection and training, for its high demands for constant performance. Though the NZSAS is closely modelled operationally off the British counterpart, their selections are different. Joe Hotai, who went through both the NZ (10 days + 9 Months) and Australian (3 weeks + 16 Months) SAS selections, NZSAS was much harder. All the information I am about to share is generalized for the sake of brevity, but there is more detail on msigwarrior.com or YouTube.
