IG-88 General

The outside of the warehouse is guarded by an IG-88 assassin droid. The door to the warehouse is open, and inside you see stormtroopers. You can see part of the arsenal inside - a portable ion cannon, rows of detonators, and heavy blasters. You can't shoot into that arsenal. One stray blast bolt would blow up the whole city.

You might have to fight them hand-to-hand, even though stormtroopers are wearing armor. But you certainly can't fight an assassin droid that way.
