Whatever map, The uncap is the area where personnel and vehicles spawn in and a small area around it. In some maps like SOS the uncap by A is just the area out in the street and a little area around it, not the red zone all the way up to A. You have to just use common sense, jumping up on the ledge on lockers is considered entering uncap because there is a step or so that you can get halfway up and not be in the redzone, but there is nothing to do but fire into uncaps at that point. So it is considered entering uncap.
