The first draft of each script had to be completed no later than a week before the broadcast date to allow military authorities time to check the script's facts and censor it if necessary. A working draft had to be ready by three days prior to broadcast so that Robson could prepare appropriately. Another radio historian,
John Dunning, wrote, "Timing was everything: in the battle scenes, the actors, narrator, music, and sound had to be coordinated and cued 'literally on a split-second.'" Such precision required two days' rehearsal, which led to Sloane's leaving the show. He was busy with other programs and told Robson, "I just don't need that much rehearsal", to which Robson replied, "Everett, I know you don't, but I do." Music was "a vital feature of the show", with the style varying "from Wagner to jive", depending on the mood to be supported. Some episodes' scores were complete original compositions by Van Cleave. Robson's insistence on controlling selection of music resulted in Herrmann's being replaced by Van Cleave. One studio observer of a broadcast of
The Man Behind the Gun compared Robson's directing to a maestro's directing an orchestra, as he used both hands to bring in voices, music, and sound effects at appropriate times. His efforts to enhance the realism of broadcasts included placing two 18-inch speakers in the studio, located so that actors heard sound effects through them but microphones did not pick up those sounds. Robson said, "Now when the guns went off, the actors had to yell to hear themselves. When the planes went off with four motors going, they had to yell to be heard above it, and the actuality was magnificent." == Critical response ==
