 The two of them cooperated with another Austro-Hungarian aircrew in driving down a pair of Russian Farman biplanes; each Austro-Hungarian crew was credited with a victory.On 2 August, Jäger and Urban scored again, when the gunner used 100 rounds of ammunition to shoot down a Farman two-seater behind Russian lines; the fatal victory was later confirmed through interrogation of Russian prisoners of war.On 28 August 1916, flying with a new observer, Urban engaged four Russian planes–three Farman two-seaters and a single-seater Nieuport fighter.
