[Illustration: _Figure 68: Basic Types: Surrender Leaflet._ The surrender leaflet shown was not welcomed by the Japanese because it indicated that the Japanese soldier using it wished to surrender. This was very vulgar and depressing indeed, and few Japanese soldiers would accept such a humiliation. Except for its wording, the leaflet is good. As large as a big magazine cover, it is white with red and blue trim and can be identified readily.]
=Other Action Leaflets.= In World War II there were ample opportunities to surrender on most fronts. In subsequent conflicts, however, it is quite possible that surrendering will be physically unfeasible, because the surrenderee will have no one at hand to whom to surrender (see below, pages 248-250). Recourse may then be had to a type of leaflet only occasionally used in World War II--the leaflet which calls on enemy troops to perform some action other than surrender. The commonest of these is desertion--when it is known that enemy forces are being held in a dangerous spot by their own command, and when there is a fair probability that heavy artillery or air attack can be concentrated on the area which has been strewn with leaflets. (A bluff normally fails, and moreover discredits later operations of the same kind, whereas a successful and fulfilled threat builds up cumulative credibility among the enemy audience.) When long range weapons are used, it may be possible to address troops by leaflet before the attack, suggesting that they remove themselves, as individuals, to places of safety; such an operation would assist enemy disorganization. The author knows of no case where the Germans did this with their V-l or V-2 bombs, but figure 3 applied to both civilians and troops in the cities marked for destruction by incendiary B-29 raids.
Black action appeals may teach the enemy troops how to malinger, may present political or ethnic arguments to troops known to be members of minorities or satellite nationalities (for example, Poles in Nazi service), with the intent that these mutiny, or may--at the very end of a war--call upon enemy troops as units to cease resistance and to await a later opportunity for organized surrender.
=Loudspeaker Units.= The use of the amplified human voice developed slowly in World War II. Improvised units were set up in North Africa, in the Italian landings, at Anzio, and in the Normandy operations. At times these talked over valuable groups of enemy prisoners, but their range did not go beyond two hundred yards, which sharply limited their utility. The Navy was simultaneously experimenting with Polly Planes in the Pacific, which flew at considerable altitudes over islands and talked to the Japanese troops on the ground.
