Sounds like they need more training.
This really brings back memories. I was a working in a small Colorado mountain hospital about 30 years ago when a group of Green Berets were flown in to practice night parachute jumping in mountainous terrain. All of a sudden our little ER was full of men in camo with matching face paint and sprained ankles, knees and backs. That was my first experience at removing cactus needles from various parts of the human anatomy. The officer in charge was not especially happy with them! LOL
The lights are awful little from 12,500 ft. Get your calculated release point pick the spot and go. Hope you get the wind drift right and follow the low man.
Thats why it is training.
The world is a Drop Zone and everybody is sure to hit it sometime.
