     Wait, I was killed by... a facility guard throwing the ball?! So, wait, I got teamkilled by SCP-018, which is good 'cause that's on my list of ways to die, but it was by a teammate?! I mean, that works, but I didn't think that was possible - OK!

     Albeit, at the time, the Type 93 would go on to be the central star of the most spectacular teamkill of the war, when the cruiser Mogami fired a salvo of six Type 93s at the cruiser USS Houston, missed, but, with their long range, the torpedoes quite happily motored on and blew up four friendly transports and a minesweeper. Yeah, not such a good day.
