OK I'll start!
I was playing a Harpoon game at a friend's hobby shop one night. I was on a week's vacation from tech school and this was one of 3 weeks a year i coudl game during the week. A friend had offered to Ref so I could comand a sub and actually play a naval game.
The scenario was that I was returning from patrol with a Los Angeles class attack sub. Last mission before returning to port in Bangor Maine was to sanitize and shepherd a boomer off the contenintal shelf before returning to home port. We knew we would have Russian opponents but didn't know what to expect. Also I didn't know what kind of idiot the Boomer commander was.
His first bright idea was to tool along the surface trying to look and sound like a Merchant vessel. I broke protecal and told him that his tactic wouldn't work becasue his sound signature would be in any Russian's computer and he was making it easy for the Russians to target him.
He finally submerged and dropped to 15kts. I had started picking up a sub in my first convergence zone (CZ) and was working on an ID. This ws difficult because teh convergence zone is only 3NM wide and I had to keep trying to move the zone with my target.
I positioned myself between the Boomer and the target and the Russian was now flirting on the edge of passive range. The Boomer was still in shallow water so there were no convergence Zone and the Russian would have to get closer to detect and follow the Boomer.
As my friend kept feeding me info I expected to get the boomer on my sonar but there was nothing. I deployed my towed array despite being on the edge of the shelf trying to not loose my position and locate the other US ship.
When i finally found and classified this clown he had spent the last 6 turns doing a tight 360 in the mouth of Cumberland sound. Every sonar contact he would order a 90 degree turn. Instead of getting a classification on me and getting this game done he was trying to hide from his escourt!
Even the uncontrolled laughter of my friend when we turned in our orders didn't give this guy a clue. The next turn I lauched 2 MK 48 torpedos and blew him out of the water myself.

I pray for Peace on Earth Good will toward men. Till then one round HE fire for Effect!
