I read a book 20-30 years ago. It was a team of SF guys going on a mission. I remember one guy carries a shotgun.

I remember the title had something  to do with a hand or fist or fingers or something like that. I think.

Ring a bell?

The five fingers

Yes.

Gayle Rivers is the author.  Been looking for it myself.

"Gayle Rivers" is a total phony.

He was in the Australian Army quartermasters and his unit served the Aussie SAS.
He picked up just enough of the lingo listening to the troopers to sound like he was an operator.
He "left" the Aussie army one step ahead of being court marshaled for the old quartermaster disease of selling government property.
Other sources say he was in the New Zealand army quartermaster corp and his real name is Raymond Brooks.
This source says Brooks once tried out for a SAS reserve unit but failed.

He reinvented himself as a special operations anti-terrorism expert and often appeared on British and American TV as a former operator and expert, right down to "protecting his identity" by wearing (honest) a black hood.

In one of his last books he said that he'd just gotten back from teaching underwater demolitions to the US Navy SEAL's.
This was big news to the SEAL's because they're the worlds experts on demolitions and they do the teaching.
One of the SEALs contacted some friends in the British SAS to find out who this clown was, and they found out who he really was.

Rivers was exposed as a total liar and fake, but even after the British media told the US media he was a fake they continued using him as an expert for almost a year.
Reportedly some US and Brit special ops people finally had enough and got word to "Rivers" that it would be very good for his continued health to stop appearing and writing books claiming to be a special operator.

He dropped the "River's" ID and has apparently written other books under other names.

His first book "The Five Fingers" was a horrible joke pretending to have been taken from "real events".  Giving it a read you're are left wondering how they carried all that ammo over most of Asia and how they could walk that far.

That’s it. Thanks.


Yikes!  $150 on Amazon.

Interlibrary loans.   Azzwholes jack up the price on out-of-print books.

 It was a Fun Read.

Here are some affordable copies on a good site for used books.
