When I first saw the cover of JANISSARIES by Pournelle, the soldier reminded me of the Airfix 1/76 Paratrooper box art. I wasn't far wrong.
CIA backed US Mercs are fighting in a faux Angola and rescued from destruction at the hands of a larger Cuban force by a extra-terrestrials.
The Mercs are transported to another planet where, led by a Christopher Walken wannabe, mayhem ensues.
I know why I pushed this book to the back of my mind, but playing around with some AK47 figs this morning, Janissaries aptly demonstrates that ANYTHING can be turned into a Sci Fi background. Something to bear in mind in these increasingly tight economic times.
