During the repeated brief passes it is occasionally possible to get off what is called a "snap shot" (A snap shot is an opportunistic shot of brief duration, brief because of the rapid change of the LOS () to the target caused by the aircraft's maneuvering in different planes of motion. The preferable "tracking shot" opportunity lasts longer; as long as the attacker can maintain a constant LOS to the bandit, accomplished by maneuvering in the same plane of motion as the bandit. The process of getting into the same plane of motion as a bandit and setting up a tracking shot is called "getting into the saddle" or "saddling up".) at the opponent fighter, although due to the typically close range of the scissors, usually only guns may be used for this "snap shot". This process of 180 degree rolls and reversed turns can be repeated many times while each pilot seeks a positional advantage through energy management, and seeks to avoid a disadvantage.
