The QF 1-pounder (Quick Firing) was the first autocannon, developed by Hiram Maxim of Great Britain. Also known as the "pom-pom" due to its iconic sound, it served as an anti-infantry and anti-aircraft weapon. It was fielded by many nations during World War I, including the German Empire and the United States, as well as their respective navies.
It is a devastating piece of anti-air weaponry and one of the more effective ground-to-air weapons against the Airship L30. Using explosive flak rounds, it can easily damage any aircraft within range, and a direct air-to-ground counter attack would be difficult due to the intense shaking caused by the explosions.
The gun lacks physical shielding and leaves the gunner exposed while using it. It's also not very effective against ground targets.
It was first demonstrated at the "EA Play" event on June 12, 2016.
Until the Battlefield 1: They Shall Not Pass patch, AA rounds also inflicted impulse on struck planes, potentially driving them off course. As of the patch, AA rounds no longer impel, but merely damage.
