From the back of the book:
Attention Troubleshooters! Your friend The Computer has selected you for the privilege of participating in a suicide mission of marginal importance.
You will be assigned to masquerade as a crack team of communist traitors in a live ammunition practice maneuver with 12 elite vulture squadrons. As fatalities are expected to be overwhelming. All clones in each family will report to facility rapid reinforcement.
Please proceed to troubleshooter headquarters. Please bring all personal effects in a small box. Failure to report merits summary executing by slooooow torture.
Thank you for your cooperation.
