Single Direct Attack (SDA/SAA)
SINGLE DIRECT ATTACK, or SDA as it is often referred to, represents the ultimate in JKD sophistication. Single Direct Attack is a single offensive action which goes directly from where it is to a desired target, without any attempt to disguise the motion. This attack might be a finger jab, a punch, a kick, or even an elbow or knee.
Although technically SDA is the simplest method of attack, it's also the most difficult to complete successfully because the speed and timing of the attack, as well as the penetration of the opponent's defenses must all be perfect. SDA relies on superior speed, excellent timing, good distance regulation, and precision, all of which should be supported by good defensive covering.
Single Direct Attacks are usually executed when, for some reason, a particular target area has been unintentionally left open by an opponent, or when an opponent is uncovering a line. Success in using SDA also requires a correct evaluation of the defensive reflexes of the opponent.
The following are important factors concerning the use of any type of Single Direct Attack:--
1) Speed -- You literally "jump the opponent's consciousness", and beat the opponent to the punch. This means you have to be fast. Both reaction speed and movement speed can be increased by including speed development exercises in your training sessions.
2) Timing -- A Single Direct Attack will stand more chance of being successful if it is timed well. Some good times to attack an opponent are:
a) when an opponent is physically or mentally unprepared, such as if he relaxes his defenses or concentration to slip for a moment.
b) when an opponent is recovering after his own attack.
c) when an opponent makes mechanical actions with no tactical intent, such as a feint or a change of engagement.
It's important to remember too, that the timing of your attack must also be related to the speed of the opponent's movements if you do not want it to be caught up in them.
3) Economy of Motion -- If your attacking motion is both very economical and non-telegraphic, it will surprise the opponent, thereby significantly reducing the opponent's chances of parrying it in time. Eliminate any motions that might giveaway or signal your intentions to the opponent.
4) Distance -- If you're too far away you won't reach the opponent, and if you're too close the opponent may reach you first. So try to control and regulate the distance between yourself and the opponent.
5) Defensive Coverage -- No matter how good you are, you still run the risk of the opponent managing to counter your attack with his own. So support your attack with good defensive coverage.
SINGLE ANGULATED ATTACK -- A variation on Single Direct Attack is Single Angulated Attack, or SAA. A Single Angulated Attack is an attack which is thrown at an unexpected angle, and is done by positioning your body in relation to the opponent in such a way that an opening results. Sometimes it is preceded by a feint, and sidestepping or some form of lateral movement is often used as extra support. Like Single Direct Attack, Single Angulated Attack should be supported by good defensive covering.
