Don't have 100 billion to spend to be able to hot drop on someone using titan bridges? The next best thing is via cloaked black ops battleships that can bridge vessels such as stealth bombers into a fight from far away distances.
The setup is typically done this way:
- Multiple cloaked alts spread out in low sec or high sec ["hunter killers"]
- Once the cloaky hunter finds a target, he warp scrambles it and lights a covert cyno
- Black ops fleet drops in and kills the target
- Fleet cloaks up and disappears
- Fleet can then bridge back to the staging area using a return covert cyno alt
Here's a great example of a well executed BLOPs attempt:
