The Secondary Weapon Bug

   Select the unit, Attack Tanks and AT-AT's work best, and prime secondary weapon by pressing T-key, select target to fire at, repeat process as quickly as you can while the weapon charges and continue while it fires until it stops firing. As you can see from the second pic I got off 4 shots. Click the image for a fullscreen screenshot.

   Take over an enemy base or structure, this may work with your own bases but can be more difficult do. After taking the base, exit all units, put the damaged droid in the structure first, then some hurt troops. The droid will go back to full health and start to heal your troops.
