Last December, footage emerged of an AH-64 Apache helicopter being engaged by surface to air missiles over Yemen, breaking apart and falling to the ground. Reportedly both pilots were killed.
Regional news outlets have been calling the Apache a Saudi aircraft; but it is just as feasible that it could have belonged to the United Arab Emirates, as both of the allies maintain AH-64s in their military arsenals and are engaged in the fighting over Yemen. The Apache was apparently shot down near the border between Yemen and Saudi Arabia, however, adding credence to the assertions that the downed chopper was indeed Saudi.
