It seems to me that debate getting out of hand, let's refocus :
One more thing : May be some out seems to consider that the idea of a "jump" control came from some of (relatively) young and "nervous" BF3 player (but my son is, no offense ;) ). In fact, I'm 50 yars old, play Arma serie games since OFP, don't like Battle Field, Call of Duty,... games. I had the idea of a jump drive because of circumstances encountered during my years of playing (damn, 12 years !). I would be happy if this clarification has a chance to stop this -BORING- "war" between "pro-BF3" and "pure-Arma" players I began to see here.

Couldn't say better !
@harold5187
"Real combat soldiers do not go about jumping in combat." Well... one of my friend is an old "red beret" (commando-glider) and didn't say that (and vote up, also ;) )
@fbiss
"There is no good reason for having a jump in this game."
Gratuitous assertion. I request explainations (for up and down voting), so that everyone can get an idea of the relevance of a "jump" control. Thank you for having nothing explained...
"Give me ONE good reason why there should be a jump"
Give me ONE good reason why there SHOULDN'T be a jump ? The job isn't to convince you especialy, otherwise, convince me ! I'm pleased to read remarks such as those Huorn writes, and open-minded enough to say that he's right, and therefore accept his downvote. Again: you said nothing.
