The Ottoman Air Force of their Army and Navy during WWI had a wide range of aircraft types from several nations.
Germany:
Fokker
LVG
Gotha
Rumpler
Albatros
Pfalz
Halberstat
France:
Morane-Salnier
Voisin
Nieuport
Caudron
Britain:
Farman
de Havilland
Bristol
Russia:
Grigorovich
So the armament of the types supplied to the Ottomons would be the same as used the by countries they were purchased from.
