Dear developers! All these bugs are related to Prone position and they all spoil the impression of the gameplay in Arma3. This is old bugs, the player's eyes are already tired to bleed! Please remove this shame from the game, because THOSE BUGS spoils the impression of such a serious game as Arma3:

Approximately every third/fourth AI-soldier, which will killed in the prone position, will fly unnaturally will bounce up as if it is made of cardboard, and the every fifth or sixth corpses fly into space (5-10 meters up!) If you can not configure your regdoll more than 6 years, just turn it off! It is so simple!

When the AI is in a prone position, it can take an unnatural position when it is aiming for a high located targets or an air vehicle. All is need - is to change the available vertical angle for shooting, when the AI-rifleman is in the prone position.

When a player becomes prone, before a stone or other obstacle, player gets a unnatural position of Cobra.
The problem is not only that it looks absurd, but that the player may suddenly lose the ability to shoot from prone position.
