#1--all time for me was in World War II Online---East Armybase, Brussels.My squad and I were just kinda snooping around(outside) the AB,not a thing in sight,and it was superquiet.Brussels was theirs(Axis) but we weren't capping the AB,just looking around to report what we could find out.We knew they were using the place because 2-3 panzers and a halftrack with 5-6 Jerries had passed us on our way through town(from South AB).
--I decided to get a closer look,I let my asst. gunner know I was moving up 20 feet or so.I go from prone to crouch and this Jerry runs right through the door I'm about to egress through,maybe 10 feet away.
In those days in WWIIOL you had to bring up your weapon with a keystroke,it was either space or shift,I forget,but you could map it.
My buddy got him right away.But I was just crouched there...having a heart attack.
