If there are two SBDs, concentrate your team's fire on him. Repeat the process until he is destroyed. After he melees, he will resume shooting at you. While he is swinging his arm, fire at him with your blaster. Then melee him and back up before he can hit you. Additionally, to defeat a Super Battle Droid, run up to him while he is shooting at you. This should shut them down or put them on the ground. Throw two electric grenades and fire a quick bust from the DC-17. You should also use your DC-17's anti-armor attachment.
Once they are being shocked by the EMP, throw Thermal Detonators to deal extra damage. Use your EMP grenades and concentrate your men's fire on them. Note: If there is more than one Droideka, stand so that you are in line with as many of them as possible so that the others cannot see you. Kill it with melee attacks to save ammunition. To kill a Droideka easily, stand as close as you can to it, and directly in front of it (between its gun arms).
