I've found nothing about it in the forum, so my apologies if I messed up...
I would like to suggest the capability when you're at least two guys close enough together to trigger a do the "give a leg up" in order to go over some walls or to get in over building. In french we call this "Faire la courte échelle", I'm not sure about the english expression.
I don't know how far we can push this functionality but the basics of doing it can already be nice. Meaning going over small walls, or at least check over wall and why not firing with gun ? And a guy on a building could help another to climb ?
What do you think about it ?
