The concept of pursuit geometry between attacker and defender in the ACM environment is basic to
every tactical maneuver (Figure 4). Pursuit is defined by the attackers velocity vector relative to the
defender. All pursuits control closure in some way.
Lead pursuit increases your closure rate on the bandit and usually results in decreased nose-to-tail
distance. It also solves for a guns firing solution. To employ lead pursuit as the attacking aircraft,
position your nose ahead of the bandit.
Use pure pursuit to maintain nose-to-tail separation on the bandit, and to acquire a lock-on tone for
an IR missile shot. To employ pure pursuit as the attacking aircraft, position your nose on the
Lag pursuit decreases closure rate on the bandit and usually results in increased nose-to-tail
distance. Lag pursuit allows you to maintain your energy and may cause visibility problems for the
bandit. To employ lag pursuit, position your aircrafts nose behind the bandit.
