Handbill distributed by US Forces during the invasion of Grenada. The picture, taken the day after the invasion, on October 26, 1983 – includes (foreground) an Army Psychological Warfare leaflet prepared in advance and dropped by US Air Forces during the invasion of Grenada + and (background) Army Rangers marching through on day two finding the leaflets on the ground. Army Psychological Warfare units became operational on the island a few days later, to operate the AN/TRT-22 radio transmitter that replaced the Radio Grenada transmitter destroyed during the fighting. The “handbill” was also handed out during the invasion. Photo: EDomingos (talk). Public Domain. Source: Wikimedia Commons.
