Why are the SAS in Ukraine?

Peter Hitchens has some very good questions:

Who decided to send the SAS to Ukraine? What are they doing there? What would happen were they to be killed by Russian forces, or captured by them? And what was a British surveillance plane, capable of carrying 30 people, doing over the Black Sea last September, when a bungling Russian pilot almost shot it down, only failing because his missile was a dud? What would have happened if the missile had worked, and many British servicemen and women had died?

NZ SAS Professional - Operation Burnham

For a decade the New Zealand SAS have been subjected to attacks on their conduct during Operation Burnham in Afghanistan. NZ media have continued these attacks (see the link below). However, buried in this article is the following snippet; the SAS did nothing wrong, they acted professionally.

The SAS soldiers have not been found to be directly responsible for any wrongful civilian deaths, and the report said they acted professionally during the raid.

Alleged New Zealand War Crime

Journalist and writer Nicky Hager has written an explosive new book launched today. Titled, Hit & Run, it describes a NZ SAS revenge raid in Afghanistan which was supposedly approved in advance by the Prime Minister at the time, John Key.  Was the expected launch of this book the reason for John Key's surprise resignation?
