a ?? re: the score for a particular mission:

Guys:

One of my favorite themes to this game (It's up there with 'Standoff' & 'Battling Deathfang') but I can't find it...it's the bit that's played during the Proxima 1 mission when you're trying to defend the medical transport 'Tranquility' from the fighter attack....any idea what it's called?

Thanks ahead of time.
