Amry was a Coruscant Security Force police officer on the world of Coruscant, and identified as male. By the year 18 BBY, Amry, a officer trained for combat, had risen to the police rank of sergeant and commanded a Special Weapons Team unit. During 18 BBY, Amry and his special ops squad went with Prefect Pol Haus and Lieutenant Kalibar Droosh to what they believed was a criminal safehouse situated within a maglev train. The train turned out to be booby-trapped, detonating and injuring many of Army's subordinates.
The first mention of Amry occurred in The Last Jedi, a novel penned by Michael Reaves together with Maya Kaathryn Bohnhoff, which became available on February 26, 2013.
