Dude, I remember a mission where I had a guy in Powersuit Armor fighting one single alien, but on the Alien's turn, two more aliens flanked the powersuit guy from either side and fired at him, but he soaked the damage. He was down to 4 health and had 5 fatal wounds (!), so I decided that he should go out with a bang, and the only explosive on him was a High Explosive.
...You can guess the rest of the story.
I laughed WAY harder at this than I should have. I was imagining a squadie all burnt to hell saying "ALLUH AKBAR" and blowing himself up... Terrible.
I had a few operatives that were total characters. Armand Jackson... How can I remember his name so well but forget my birthday??? Armand was a grunt who seemingly had a knack for causing explosive havoc. He was from the the uncanny valley of having max starting strength and max throwing accuracy. I would quite regularly use him to relay grenades or throw them in crazy positions to bust cover or flush an alien. Before long I was loading him down like a mule and he got hulk strong. Once he hit like 65 strength he would just He-Man an HE into where ever. Once he threw 3 in a turn and brought a building down and racked up 6 (yes 6 )kills in a turn.
I had an operative who was death incarnate. Wounded a dozen times, and was my aliennapper. She would run up and poke the Xenobear with a stick until it quick twitching... hilarious.
But to answer your question, by some strange twist of fate I had a guy autoshot and kill three sectoids. I was aiming at one, missed and hit another killing it. Second shot hit killed intended target and last shot sped off into the dark... striking a third and dropping him. I dubbed him "Tailor" for the brave little tailor doing SEVEN IN ONE STROKE!!!
I used to regularly shoot across the map with a rocket sniper I had groomed, until he rounded Pi to 3 and went 'Splode.
Playing TFTD I had a sub that had a one tile hole in the rood and was next to some scaffolding rock bullshit so I used that as the entry point. This was before I had Mag Ion armor so I spent two turns crawling these guys up there and had them jump in. I thought " HA! I got 'em" and the first guy landed face to face with a Xarquid. DOH! yeah he died... But his BUDDY! well he landed and gutted that squid with his vibroblade.
I once forgot to put more men on my sky ranger after a particularly nasty mission full of kills and wounds and had ONE guy on the ship when I dispatched it to a terror site. Through sheer fucking luck and a few wise decisions and patience I managed to clear a terror site with one guy. It took me like 85 turns to do it, so much collateral damage but HOLY SHIT I did it. That guy eventually made Captain through attrition.
I shot a cyberdisk out of the air and landed on the gas pumps on a terror site killing two sectoids and revealing a third who just panicked.
