Amil Karsk was a pilot of the male Human species. He fought for the Rebel Alliance throughout the Galactic Civil War. Before the Battle of Yavin, specifically in 0 BBY, he held a position within Red Squadron.
Karsk achieved his fifth confirmed destruction of a TIE Fighter during his fifteenth combat flight as a Rebel pilot. This particular mission involved an assault on an Imperial convoy, which had a Nebulon-B frigate as its escort. Simultaneously, Biggs Darklighter, who was on his inaugural mission, also asserted that he had eliminated the same TIE Fighter, marking it as his third kill out of a total of five. Biggs conceded the confirmed kill to Karsk. Subsequently, Biggs provided Karsk with the third item from any group of five that Biggs obtained. Later, in 0 BBY, Biggs permitted him to undertake the third of five scheduled patrol duties, which involved protecting a courier vessel en route to Alderaan. Because of this mission, Karsk was not in space when the Death Star appeared; he perished during the Destruction of Alderaan.
