Heh. You want a really embarrassing waste of perk points? A day or two ago, I was running a PzKpfw IV into A28 to try to help take it back from the rooks. Sitting on the ridge south of the field, I exchange fire with a Tiger on the field and smoke him and get him to bail for a kill, run my turret around to pick off the Ostwind that had come up behind me and was plinking me, then had somebody in a plane take out my left track.
So, since I'm now a pillbox, I sight down on the end of the runway near me, take a ranging shot -- 1800 yards, well out beyond con range -- and settle in to vulch. Seven kills later, what would become #10 pops up -- a 262. He rolls about ten feet down the runway as my HE shell sails in and lands just forward of his nose gear, and *BOOM* 200 perk points down the drain, without ever getting up to flying speed, or seeing the person who blew him away.
Of course, being a stationary target, I died a couple minutes later, but ten kills capped with a 262 kill in a PzKpfw IV is definitely a high point for that day.
