The best one I did would have to be on Basrah.
My whole squad had tried to "cage in" the "village" (read the story "chillin in the village on basrah) but the whole squad except for myself had been knocked out in one of the fields after a long chase.
The insurgents were partying around the wreck of the landy, jumping ontop of it, beside it, everything, yelling and all kinds of stuff.
I was bleeding terribly, but prone in the fields I was invisible, and the noise of their yelling drowned out my coughing. I had C4, so I decided I should just go for it and do a suicide kill.
I crawled to the wreck of the landy, put my C4 on it, and crawled away just a little bit, even though it wouldn't do any good.
BOOM! Took out two whole insurgent squads (and myself) with a lone C4 while they were celebrating their kill over the landy.
Much surprise and "lol"s are typed over the chat, I claimed the responsibility of the bodies littered in quite a radius.
One of my favorite memories. Be sure to read the whole story at
