You know who I think? The New Zealand SAS.
Seriously, outside of the British, who has taken over the country once in its history? Even the Australians are kept at bay, and they're pretty badass themselves!
Don't kid yourself that NZ could repel any determined invasion force. Even including reserves and those currently deployed, the total number of men in the combined NZ militaries is <12k.
For instance, once the
12 ships comprising your navy have been sunk, the attacking force could sit offshore and destory the place with cannon fire and arial bombing.
On topic, I'm going to have to go with other.
From the units of which I am aware, I'll say the SASR (Aussie SAS) - widely regarded as ultra proffesional soldiors; extensive, brutal training and a 'no one left behind' attitude.
However, I've got to agree with previous posters in that the 'best' SF units is one that you won't know exists unless you're a member of it or are commanding it.
