First thing (slightly off-topic) I'd like to mention is that free fall animation for AI soldiers(AIs) is a normal stance. They start with free fall, but then they stand up. This is on first picture(pic1).

Now the AIs parachutes. After they deploy it, some of the soldiers just disappear and there are only parachutes flying (pic2, pic3, pic4). Like the bodies being detached from the parachute and going straight down, without any position change on X a Y axis, while the chutes seems to be flying normally (pic4). Turned out, that AIs bodies didn't disappear, I found them on tarmac pancaked (pic5). {F20466} {F20467} {F20468} {F20469} {F20470}
