Currently working on some mock-ups of the callout system I mentioned.

It wasn't in vanilla arma 2, It was in dayz. it made vaulting obsolete because it was much quicker to roll over obstacles. and to Vulcanexius, I don't see how this was poorly requested and if it has to be asked 90 times before it's implemented, then it doesn't deserve a downvote.

I think It may have been Dayz exclusive, but it was a nice effect.
