I really love to see a "jumping" action.
In my opinion, the more logical should be to set the "jump" command combined with the "V"/"Step Over" command, after or when sprinting : "V" = Set Over, "Shift+V" = Jump.
- It's totally unrealistic to see a man suddenly stops and step over an obstacle. Try to run (Turbo: Shift+W) then, without releasing "Shift+W", press "V" : because the "V"/"Step Over" command overrides the run command (fortunately !), your man stop, do slowly his little "dance step" then continue to run... Weird !
- Jump could allow to cross a small gap, between roofs for example.
For years playing Arma/OFP games, the only way to "really" jump is the use of a script (like this one : http://www.youtube.com/watch?v=YbYusb0RshI for example, wich allow a "jump", certainly a little bit "exaggerated"). Why the "jump" command isn't implemented natively, like in many other games ? Some "reporters" could say that it's very difficult to jump with a heavy military equipment; difficult is not impossible and a little jump of 1m or 1.5m seems realistic to me, especially during a sprint.
