Tonga has troops? That is a news flash.
Tongans come from the same warrior culture as the Samoans. Many of the NCOs and SNCOs I most respected during my time in the USMC were Samoan.
No nonsense, tough and relentlessly professional. That was common enough to those I knew and worked for that it has become my basic stereotype of the Samoan people.
Oh, and that the tend to play every bit as hard as they work.
