The men of the Special Air Service are trained to be tough and super-fit. And the officers' training is even tougher, for they must command and gain the respect of their hard-fighting men.
With troops like these, you can ask them to do the impossible . . . which is just what the War Office did with Major Alecc Barber and his unit, when they sent them behind enemy lines to recover part of a secret formula for an amazing terror weapon, that could end the war in a day.
And that formula was inside the crater of Mount Etna - the biggist volcano in Europe.
Reissued in August 1980 as Commando issue #1435
