1. Ensure that you have many tacticals around the gate at the appropriate range for your ship. If you don't, grab an inty and start making them.
2. Warp to tactical and cloak up.
3. Pre-align to warp out safe. Do not use citadels as you will have a weapons timer.
4. Decloak and shoot the tackled and/or bubbled guy(s) on the gate.
5. Warp out to safe if/when people get within 100km of you. Warp cloaked if you are a Tengu.
6. Go back to Step 2.

Iron is default ammo, spike if you know you'll be shooting big things.
