I have to agree with this request. Let me refine the request a little from my own perspective.
1- When the soldier lands and falls prone to the ground, for gods sake, leave it that way and give the player control over his character immediately. Do NOT play the "standing up" animation after the player hits the ground as it is utterly unrealistic and unnecessary. This behavior only hinders the player to react quickly to incoming enemy fire when landing in a hot zone while also exposing him unnecessarily to the enemy fire by forcing him to stand up when he shouldn't.
2- Get rid of the wind effect while parachuting and the buggy wind-drag behavior when hitting the ground. When you hit the ground, you are dragged over the map like a buggy object in the game. This is a nice attempt to simulate reality where there is wind and the parachute drags you while landing, but it completely fails. Let's be coherent here. There is actually NO WIND in Arma 3. Bullets aren't affected by any wind in Arma 3, Jets and Helicopters aren't affected by any wind in Arma 3. So why does the parachute have to be affected by an imaginary wind coming constantly from the East? Also, you are always dragged backwards when hitting the ground, no matter what direction you are facing while landing. So if you happen to land with your back to the East, you will actually be dragged backwards AGAINST the wind! How unrealistic is that? Please get rid of this behavior and stop trying to simulate wind on parachutes as it only introduces more UNREALISM than REALISM and makes the game look buggy.
