It consists of a hard turn into the direction of attack, to generate angle-off as rapidly as possible to present the most difficult target. It is used against an attacker who is about to achieve a firing position (or already has). If the break succeeds in forcing the attacker to overshoot, the next maneuver is the Scissors. The speed loss attendant on the hard turn aids his chances of forcing the attacker to overshoot, as does the smaller radius of turn, but oft-quoted maxims such as 'speed is life' act as an inhibitor. The defender can use a maximum-rate sustained turn in which he does not lose speed, or the hardest possible turn in which he almost certainly does. Two forms of break are possible, depending on the circumstances of the attack. The defender should also alter his plane of flight to make himself a more difficult target. To execute a split S, the pilot half-rolls their aircraft inverted and executes a descending half-loop, resulting in level flight in the opposite direction at a lower altitude. It is difficult for him to pull his nose around at high angles of attack to achieve a firing solution. The split S is an Aerobatic maneuver and an air combat maneuver mostly used to disengage from combat. To do this he must tighten his turn, which increases his angle of attack.

The attacker may be able to cut inside the turn but he is forced to pull lead. Our systems incorporate the latest technologies and offer the most sophisticated training experience to aircrews. The break is always made towards the direction of attack, This generates 'angle-off' as quickly as possible which makes the defender a difficult target. For more than 50 years, we have been serving the national security interests of the United States and its allies, growing to become the world’s leading provider of Air Combat Maneuver Instrumentation (ACMI) training systems. Its purpose is twofold: to spoil the attacker's aim and to force him to overshoot. This is used when an attacker is first seen approaching or is already in the cone of vulnerability.
