Are Observers Useless in Bolt Action?

Daniel talks about his experience using Forward Observers and tries (poorly) to get Tabletop simulator to play along! If you think these units are over costed, hold little value or you don't have ideas of how to use them, this video will lift the veil on most of their uses and applications for you to learn from. I've found them a very useful unit to include, although you need to consider whether it will suit your play style. Comment, critique and give feedback on how you might otherwise use Observers or whether you avoid them completely.
