If the attacker is closing fast and is caught by surprise he may easily fly through and end up in front, the positions reversed. If he attempts to follow the barrel roll, he will probably end up high and wide of the defender who can then turn in towards him, forcing him down and in front. But woe betide the defender who attempts a barrel roll in front of a slowly closing attacker who will follow him through the maneuver, ending on his tail in easy gun range. His only recourse in this event is to jink.
The High G Barrel Roll is a difficult maneuver to execute successfully, and is in fact easy for the attacker to counter. It will only work if the attacker has been led into, or is in, a high angle-off, high overtake situation.
The High G Barrel Roll can be very effective against an attacker closing fast from astern. Commencing with a break turn to put the attacker in a high angle-off position, the roll is then carried out in the opposite direction to the turn.

The high-speed yoyo is a very difficult maneuver to perform well, and demands perfect timing and precise execution. If it is commenced too early, the defender can counter by pulling up into the attack. If started too late, the attacker is forced to pull up at an excessively steep angle to avoid overshooting. This allows the defender to disengage by diving away. A common fault in executing the high-speed yoyo is not pulling the nose high enough. This can result in the attacker ending directly above the defender. Some pilots find that they obtain better results from a series of small yoyos than one large one. A variant on this maneuver, used to prevent overshooting or to reduce the angle-off, is the rollaway.

LAG PURSUIT ROLL
This is used when at close range with a high overtake, high speed and high angle-off. The defender gets the nose high and rolls to the outside of the turn. He uses maximum g to pull the nose up and towards the target. This puts him in a ± 30° angle-off missile envelope.
When overshooting is mainly the result of excess speed, position can be maintained outside the radius of the defender’s turn by matching his rate of turn, thus maintaining both speed and initiative. The pursuer is hidden beneath the defender’s tail, which could cause him to make an error. This is called lag pursuit.
