There are several kinds of jump employed in different types of circumstances, e.g. lalo (low altitude low opening), halo (High altitude low opening), static line (line attached to aircraft automatic chute opening), and freefall ( High altitude high opening). State which please. Below is a table of Newtons law regarding the speeds attained by falling objects or people Velocity and Distance Traveled of a Free Falling Object
The velocity of a free falling object can be expressed as:
v = g t (3)
where
v = velocity
The distance traveled by a free falling object can be expressed as:
s = 1/2 g t2 (4)
where
s = distance traveled by the object
The velocity and distance traveled by a free falling object:

Note! The velocity is achieved without any aero-dynamical resistance (vacuum). The air resistance will be significant for higher velocities or for object with large surface area to mass ratio - feathers or similar.
So to determine a time from aircraft to ground air pressures are relevant. so times can be variable. Abe
From static line height the approx maximum velocity achieved is about 120 knots (allowing for the airspeed of the drop aircraft) so your hanging time is minimal,It is then less than 1 min, in good windless conditions you can be on the ground in as little as 30 or 40 seconds sometimes faster, static line method is in general used for mass insertions.
Halo and lalo and freefall are used mostly in single or team covert insertions, particularly the lalo and its usually done over an expanse of water as it is a highly dangerous method of insertion, it's beauty is however is that there is far less chance of detection as the hanging time is minimised.
Halo is the most used method for covert over land insertion. It is done normally from a fast high flying aircraft. There in terms of knots great speeds can be achieved. Most covert insertions are also made in the hours of darkness your only height indicator is the altimeter that you can see Hence its very hard sometimes to choose your landing site.
Halo exit points are normally several km away upwind from the landing area or dz and you literally fly yourself to the target area hence great speeds are achieved in doing this
Rangers generally do not employ HALO/HAHO insertions; that's more an SF bag. The Rangers are a raid force, and when they do airborne insertions it's a conventional static-line jump. The standard jump height is 1,250 feet at an airspeed of 120 knots. From that height it takes about 45-60 seconds to get to the ground. Hanging suspended in the air for that amount of time, making yourself a nice easy target to enemy riflemen on the ground, is obviously not desirable in a combat-jump situation. Rangers typically conduct combat jumps at an altitude of five hundred feet, as was the case during the combat jumps in Grenada (Operation Urgent Fury) and Panama (Operation Just Cause). Low-altitude static-line jumps are inherently risky, as there is little to no time to execure any corrective action in the event of equipment malfunction, and therefore require two-star-level approval.
i've seen paradrops from five hundred meters, static line where you jump, hang and bump into the ground..
i'm pretty sure rangers dont do the HALO as that's a small unit insertion method, not company sized paradrop.
the lower, the better as the drop is less scattered (and less exposition to SAM - the flyboys want to get home, too).
imho, the optimal jump height is between 800 and 1000 meters above the DZ.
edit> 800-1000m, for training purposes. enough time to resolve parachute troubles. like tien bien said.. hanging there while there's some shooting going on would not likely be the pleasant experience. end of edit
the actual vertical speed of the parachute is (depending on construction) somewhere below 6 meters per second, subject to total mass of dropped payload (the heavier load, the faster the sink rate). i with my 70 kilograms could conveniently land a round chute without doing the "impact roll" [dont know exat english term]
so, for these values, consider the ROUGH estimate to be "you're down in less than two minutes and when all works fine it will take more than 15 seconds"
@Skunk>; indeed, meters is the value. i wrote what my experience is. actually, we were even doing round parachutes "xcountry" flights as well as stabilised freefalls from 2 kilometers.

Airborne Rangers from the 75th only do static line. The Rangers you see doing HALOs and HAHOs are Rangers from the Regimental Reconaissance Company.

@Casper...500 meters? try feet.
Training jumps are anywhere from 1000 - 1200 feet. Maybe as low as 800.
Combat jumps are anywhere from 500-800 feet. At that height you have about 5 seconds from when your chute opens until you hit the ground.
I have served 4 years in Airborne assignments out of my 23 years in the Army so far....I have never jumped higher than 1250 feet
Wine is correct. Also the only Rangers that generally do HALO would be those in the Ranger RECON detachment.
The only time you'll jump at 1250 ft is airborne school
Training at your unit you'll jump at 800 ft
In combat you'll jump between 400 ft and 800 ft
Only RRD does HALO
