I have a question about combat load jumps. What is the difference from lowering your load when you are about 50 feet off the ground compared to when you are actually supposed too? Does this stop you from swinging or is this just a personal thing? I have some friends that swear by it and I have also watched it happen on some training videos.

| Back when I was jumping it was tree top height or ~100ft. I know some guys like to ride their rucks in but I have no idea why. I've also seen people pop their rucks at 500', which is just asking for trouble. From a jumper's perspective there's not a whole lot of difference between 100' and 50'. Problem with trying to do it at 50' is that then you are messing with your ruck when you should be putting your legs and arms in the "prepare to land" mode.

Thanks, I didn't really think there would be a good reason to do it, actually more dangerous than anything. But I thought maybe it was just one of those things they don't show you at school, but everyone does anyways. Now I just have to learn how to flare my MC1-1C chute cause they really didn't teach me how to use the toggles and my one jump with it wasn't exactly picture perfect.

Well according to the manual (which I helped write) FM 57-220. I know it's been replaced but that's the one I helped write. You released the ruck between 200 and 100 feet above the ground. NOT TREE TOP LEVEL.
When jumping the following chutes the jumper 4th point of performance is "Prepare to Land"
T-10-Series. When he is about 100 feet above the ground, the parachutist checks the direction of drift and pulls a two-riser slip into the wind. He holds the risers firmly against his chest and presses his elbows against his body. He keeps his head erect with his eyes on the horizon. He keeps his legs slightly bent and knees unlocked, and he keeps his feet and knees together with the balls of his feet pointed slightly toward the ground. He maintains moderate muscular tension in the legs, which absorb a significant portion of the landing impact, and he avoids becoming stiff or tense.
b. MC1-Series. When he is about 100 feet above the ground, the parachutist turns and holds into the wind. When nearing the ground, he holds the control line toggles at eye level. On impact, he holds the toggles, rotates his arms into his body, and executes a PLF.
Whether using the old "H" harness or the new single point release system the ruck is released during the 3rd point of performance "Keep a Sharp Look Out During Descent"
Releasing the Pack.
(1) Upon exiting the aircraft, execute the first two points of performance and, during the third point of performance, release all tie-downs.
(2) At 100 to 200 feet above the ground (during the fourth point of performance), check below for other parachutists, then pull both free-running ends of the D-ring attaching straps, allowing the ALICE pack to fall the length of the lowering line.
The reasons are simple "Jumper Safety".
If you release the ruck to high then it become an entanglement danger to other jumpers. I've seen many jumpers become paired up when their lowered ruck became entangled in the suspension lines of another jumper.
If you release the ruck below 100' your wasting your time trying to pull a riser slip or turning your canopy into the wind and preparing to land, therefore endangering the safety of yourself.
I suggest that if you are active and have not read FM 3-21.200 you get a copy and read the manual. You would be surprised how much good information you might find.

You don't flare MC1-1 canopies. You turn them and hold them into the wind to slow your decent and forward movement. You turn your canopy into the wind at approximately 100 feet. If you don't know what the direction of the wind is, just let both riser toggles go loose and the canopy will turn and run with the wind. Then either pull a left or right and turn 180 degree and hold there by playing back and forth keeping the canopy facing into the wind and at about 10-15 feet pull left or right to and turn slightly so that you can do a side PLF.
