 It was known a half-hour before the hostages and kidnappers had even arrived at Fürstenfeldbruck that the number of the latter was larger than first believed.Despite this new information, Schreiber decided to continue with the rescue operation as originally planned and the new information could not reach the snipers since they had no radios.It is a basic tenet of sniping operations that there are enough snipers (at least two for each "known" target, or in this case a minimum of ten) deployed to neutralize as many of the attackers as possible with the first volley of shots.
