What does "BT" mean?

I've noticed these initials at the end of briefings for missions. Does it mean "Good Luck" as does Bravo Zulu means "Good Work"?

I am also curious as to what this means! I was ready to jump in this thread and yell, 'Bathythermograph!' so I'm glad I read your post first :haha:

EDIT: Just looked up BT on an acronym finder and I found, 'Break,' so I'm assuming that's what it means.

It's been half a lifetime since I used morse, so I had to look this up BravoTango [barred] is a line break, or new paragraph.
