Wackett used his modified BE2c to good effect on several occasions. He once gave the enemy pause when while on a reconnaissance mission he was attacked by two Rumpler C.Is. Wackett flew towards them firing the gun and the Rumplers broke off the fight. On 11 November 1916 he was in his BE2c on a 7-hour bombing mission to Beersheba with four other BE2s and a Martinsyde G.100 when the formation came under attack by two much superior German aircraft. Wackett was able to use his aircraft to assist the Martinsyde in defending their comrades and fighting off the attack. On the night of the 14/15 January 1917, 16 Jewish workers (mostly masons, carpenters and plumbers) who had been working in Beer Sheba under the Turkish Military Authority, were sleeping in a railway carriage at Beer Sheba Railway Station when a RAF BC2c dropped a 45 kg bomb very near the carriage killing all of them. Later investigations by British and Australian air-force historians confirmed that the pilot was an Australian. Further investigation and in-depth study of British, Australian and Turkish records by researcher Dr. Ilan Gal Peer, confirmed that the most likely pilot was Wackett of Number 1 Squadron attached to EEF, who believed a non-existent ammunitions shed was located in the immediate vicinity.
