Throughout the campaign to drive the Japanese back to Japan during World War II, bomb groups would be ordered to fly ground support missions. This typically meant targeting ammo dumps, Japanese troops and supplies, antiaircraft gun locations and flying night harassment missions.The A-20 was an effective tool for these missions due to its ability to pack a punch and its light, maneuverable design.
At the beginning of April 1945, the 312th Bomb Group carried out missions to support Filipino guerrillas as well as the 33rd and 37th Infantry Divisions. In Formosa, the list of prime targets included rail yards and alcohol plants, which produced some dramatic photography. Compared to the earlier missions flown by the 312th, there was relatively little interception from Japanese pilots. As a result, the American pilots attacked various targets with gusto, destroying warehouses, repair facilities and other buildings, and damaging rail yards and alcohol plants. They used 250-pound parafrags and 100-pound napalm bombs, which started large fires that were still smoking when the 312th was 20 miles out from the target area.
Their results caught the eye of General Kenney, who awarded the 312th with a Distinguished Unit Citation for an “outstanding performance” over the cities of Kyoshito, Eiko, Saiatau, Shinei, Banshiden, Tamazato and Suan Tau. Long distance missions like these pushed the A-20 fuel range to its limits and Kenney praised all those involved in the preparation and execution of the missions. He also commended the pilots and gunners for their target accuracy “at roof-top level with a suddenness and fierceness that prevented the Japanese from offering more than feeble opposition to the devastation bombing and strafing runs…”
