I saw a documentary on WWI on Discovery.
Apperantley, some fronts were very, very cool. People went over to each other to have meals and play football. Once, some germans tossed over a rock to the britts, with a note saying "Our officers want us to fire an arty round at you. We don't really want to. We will blow in a whistle just before so you know that you have to take cover". And apperantley, the whistle came, just like the shell. No casutlies.
That'd be cool in OFP.
