Arma 3 bug that was recently discovered. This bug is from the feature that makes you sink into the ground in Arma 3. The player shrinks but the hitboxes do not shrink with the player. This feature also causes problems when people are shooting over walls. People are able to shoot over walls/rocks/objects etc. but not be seen by the player they are shooting at because they are sunken into the ground. https://www.youtube.com/watch?v=b6bWaeSN9iM video explaining how this bug works. Also shows the problem when people are behind walls. I also think this is the reason people can lean corners and not be seen when shooting not 100% on that but it's a theory I have.
