A set of white lines on the tail of a plane utilized by the penal military unit Spare Squadron in Ace Combat 7 to showcase the severity of the crime(s) committed by the plane's pilots.
As Trigger (Ace Combat) was accused of shooting down former Osean President Vincent Harling's helicopter, his planes were all painted with three lines; the most a pilot could get. Despite this, his actions during his tenure in the unit garnered the nickname "Three Strikes". After being transferred to the LRSSG and pardoned for his crimes, the three lines turned into three claw marks.
