This mod doesn't really do anything directly useful; it was just an itch I wanted scratched.
A few gamers may remember Bungie's amazing "Myth: The Fallen Lords" back in the mid-90s, which set the bar for small unit fantasy tactical combat (and a wonderful backstory/voiceover "feel" which imho has yet to be matched in any game since).
Anyway, one of its well-done (albeit depressing) features was that whenever one of your units died, rather than either glossing over it or dwelling on it, a neutral voiceover voice would just say "Casualty." And in a big battle where you were sweating bullets and your troops were dying in large numbers, having this horribly neutral voice chanting "Casualty. Casualties. Casualty." was both maddening and yet energizing. It added something.
Anyway, for no good reason I decided I wanted that in WoW, so I coded up this little mod. It's horribly incomplete (for one thing, it triggers when pets die, which I should fix, and may trigger on other things) but it did what I wanted, so I thought I'd share it. If I have time and anyone in the universe wants it to do more, I may add more flexible announcements, integration with SCT so you get a message zipping up the screen with the name of who died, etc. But right now, with its basic "casualty" message, it does what I wanted.
Note: What you have for a sound sample is me and a microphone, since the actual sound samples from Myth are not free for public distribution, so feel free to go through the trouble of replacing them if you wish.
