I can't recall off hand which soundpack had it, but there were several options for screaming paratroopers. Also, if you play around with your sounds folder, you can have separate sounds for the same things. By that I mean, different bomb release and impact sounds for fighters and bombers (Waffle has some explosions for bombers that I love), different rocket sounds, etc. I spent hours one night when my isp was down just playing around with sounds, mixing and matching, etc.
If I remember correctly, the default sounds are low quality and fewer in number to keep the download size tolerable. My sounds folder alone (using stuff from Mitsu, Fruda, Waffle, and others I've borrowed from various games I own) is around 90mb, and that's after I pared it down.
I strongly urge everyone to obtain all of the player developed sounds, and even experiment with your own.
edit: the paratroop sound is 'drop.wav'. The parachute sound when you bail is just the chute opening, and is 'chute.wav'. You could use sound recorder and your mic to alter either, and then you get to listen to your own panicked cries.
