The VDV seem to prefer their reefed drogue dispatch system which may be due to the drop speed of an IL76. I can't see it throttling back to 115kts. The drop itself from the helmet cam was about 50secs, half of it in "attenuated free fall" (about the same speed as in a tandem fun jump) That would equate to about 4000ft. The phase under the main canopy was about the same which equates to about 500ft so the release height would have been around 5000ft mark or 1500m. The troops weren't on oxygen so the mid level scenario fits.
UK Freefall qualifying height is 12000ft. Oxygen is used by the jumpers at or above this height. The terminal velocity of a para in the standard posture shown is around 120kts.
