Camping
Holding a safe position far from the fighting, which is sound play for some vehicles and a way to lose slowly for most.
Also known as camp, sitting back, kemp bush.
A tank destroyer covering a lane from concealment is doing its job. Fifteen vehicles doing it at once is how a team loses without ever being outfought, because ground taken by the enemy is spotting, position and time they get for free.
The word is usually an accusation, and the distinction it misses is whether the position contributes: a camped vehicle that covers a chokepoint is useful, one that covers an empty corner of the map is not.
