Distract Longbow by Planting Bombs
Longbow has been watching the Goldbrickers like hawks lately, waiting for them to slip up. The Goldbrickers have a major heist planned, but they need a distraction - that'll be you. Plant these bombs around one of the power transfer systems. We'll send an anonymous 'tip' to Longbow letting them know that you're up to no good.
The bombs have been loaded on a truck. The truck will take you past the perimeter security. From there you're on your own.
Mission Complete: Missing
The bombs caused enough of a distraction to allow the Goldbrickers to pull off their heist. Nice piece of work!
