In smaller units, the propaganda unit would often be placed in direct communication with a specific artillery unit, which would be charged with the responsibility for discharging the leaflet shells at opportune times. When a requesting unit asks for leaflets, and itself possesses the guns which could fire leaflet shells, it is entirely possible for the supplier to send leaflets ready-packed in the shells. However, even the most rapid shell-packing job takes considerably more time than the readying of aircraft for leaflet distribution. When it is considered that the plane not only discharges the leaflets, but delivers them from the supply point, all in one operation, it will be seen that close air-ground coordination will often do a quicker, bigger job of leaflet saturation than could be achieved by the requesting, preparing, transporting and firing of leaflet shells. =Contingencies of the Future.= This text refers to known experience. Short of turning to the field of futuristic fiction, it is impossible to provide discussion of situations which have not been known in the American Army. The experiences of the Nazis and the Japanese cannot be taken by ourselves as wholly parallel, since those peoples, under dictatorship and rabid indoctrination, produced a different kind of army from the American. What should a small-unit commander do if his men thought they had been contaminated by airborne disease germs distributed by enemy bacteriological warfare planes? How should he act if his men were told by an enemy broadcast that they would be exposed to radiation which would cause anemia, cancer, or death--if they did not surrender immediately? What should he do if he finds himself cut off from all American supplies, operating a lonely unit in contaminated or dangerous areas, and then discovers that his own men are the victims of enemy black propaganda? How should he behave if his men get the idea that they are never going to be replaced, and if they suspect (either spontaneously or because of enemy action) that the unit has been abandoned by the American government and people?
