AAT and Swamp Speeder:

It moves very fast and it can shoot two lasers simultaneously at an extremely fast rate. Its secondary weapon is a heavy laser, just like the Gian Speeder. The AAT is the Trade Federation battle droid tank. The AAT is fairly slow and shoots two lasers simultaneously a medium-slow rate. Its secondary weapon are projectile bombs.

Hint: Platinum medals:
It is also possible to earn a platinum medal by completing a level, including the secret levels, very successfully.

Hint: Diamond medals:
Successfully complete a level with very sharp accuracy, a high number of kills, three lives, all friendly saves, and a very short time.

Hint: Disruption Of Comm 4: Platinum medal:
To increase the number of destroyed enemies, do not destroy the shield projectors as you were ordered. Instead, begin firing your blasters repeatedly at the Comm Satellite. Each shot that hits it counts for a destroyed enemy. To make sure you get enough, you should continue to do so for a minute or two. When you think you have gotten enough (150-300), bring down the satellite's shields by flying towards the large tan-colored moon. You should reach a mine field surrounding what would have been your last projector to destroy. Just fly within range of a mine so that it shoots at you. Either by glitch or secret, this disables the satellite's shields. Then, just return to the satellite and hit it with your torpedoes -- you should have all of them left. If you do not get the platinum medal, the game will not show you how good your stats need to be, so you have to just try it a few times. You will not have to worry about friendly saves, your shot percentage should be easy, and you are never really in danger until the shields go down.
