Phoenix Logs/Banished Units/Banshee
From Halopedia, the Halo wiki
Multi-role attack aircraft.
The Banshee is a versatile attack aircraft armed with anti-aircraft plasma cannons and a ground attack fuel rod cannon. The fuel rod cannon can be upgraded to fire a powerful tracking plasma torpedo that is surprisingly effective against air units.
The earliest models of Banshees were modelled after the 'sKelln, a leathery winged flying predator from the Sangheili homeworld, Sanghelios. The Banished have twisted this ancient ancestry to make it look similar to an aerial predator hailing from their own homeworld, Doisac.
