Medals are achieved doing certain objectives in single player and multiplayer mode.

Go into a space battle with a wielding torch. Board the enemy ship and wait by the Y-Wing or Tie Bomber. They will not be able to fly over you while you are using the torch. Make sure to point it directly at the ship or you will just stand there and get shot. When you are done slicing into it, blow it up to get it out of the way. None of the pilots will get back in it once you have sliced it.

Out of all the Space Heroes that can be used, Darth Vader is the best. He has a powerful twin laser cannon that does a good amount of damage, has good recharge time, has wonderful targeting capabilities, and paired with a proton torpedo launcher that launches both tubes simultaneously makes for a wonderful fighter. The second best space Hero is Han Solo. He has similar abilities to Darth Vader, has but his ship is a very large target. It is very difficult to miss the Millennium Falcon even from medium range. The third best Space Hero is a tie between Boba Fett and Jango Fett. Their ships have great fire power, but poor targeting capabilities with their laser cannons. It is better to use Slave 1 for attacking the enemy carrier ship's vital areas than to battle the fighters. Try to ignore the turrets. They will shred Slave 1. Also its own laser cannons have a difficult time hitting small targets. The worst Space Hero is Obi Wan. You are better off using the regular Republic Interceptor over Obi Wan's Jedi interceptor. Obi Wans shoots faster and burns out faster. You will slowly die over time if you cannot find enemies to attack.

The Empire has the best naval fighters; it is a wise choice to select that side when in a Space Assault game. The Tie Interceptor is the best choice when deciding which of the Empire's fighters you will be using. The Tie Fighter is better suited for attacking bombers and boarding craft. The Tie Bomber is good for bombing the critical systems of the enemy capital ship as well as attacking the escort ships. The Tie Defender should be used as a support ship. Even though it has six laser cannons and more missiles than the other fighters it appears most of the time to not have target lock capabilities with its lasers. Also, it is a big target for a fighter, and can be picked off by enemy Interceptors. Do not forget to equip yourself with the vehicle repair power-up. It will repair damage done to your space craft.

Go to one of your Command Posts and customize your character so that he has a blaster rifle. Hold R when you have the Hero on the screen. Next, move the Analog-pad Left or the Right so he cannot hit you and start to fire away. Note: Make sure that you are far enough away.
