24 December 1944: the CC A of 2nd US Armored Division took Buissonville and then:
"After this action a squadron of P-38's strafed the village, probably on a mission which had been called for before the assault, killing one American officer and wounding another before the airplanes could be diverted."

21 November 1943: a Navy bomber attacked US tanks at Makin:
"Before the four tanks had dispersed, a navy bomber suddenly swung over them at a very low altitude, and from its opening bomb-bay hatch, a 2,000-lb. "daisy-cutter" fell, striking ground about 25 feet from Captain Tobin's tank on the highway. Lieutenant Gallagher, Pfc. John E. Costello, who was covering him from the base of a nearby tree, and Cpl. Elmer F. Conway, who was in a foxhole, were all killed, and two sergeants were wounded, while other tank men were injured by the concussion. By the time the crews had recovered the snipers were forgotten. They gave no further trouble. "
