This game type requires the least amount of planning, in fact it can be done with no planning whatsoever if the group is especially talented. In this type you need to kill every terrorist present to win the mission. That, combined with the fact that usually less terrorists are present than Terrorist Hunts, might make you think that this is just a scaled-down version of tango hunt. It is not. In some instances the terrorists will try to escape, and their escape will cause your mission to fail.
Some planning is necessary here, with some human players needed to cover the escape routes.
Speed is also key, because if you moved too slow the terrorists might run away anyway. To delay them silence will be necessary, the tangos will bail-out as soon as they heard trouble coming. In this type you need to assault with the specific purpose of stopping the terrorists from activating something. Again if you moved too slow and was observed the terrorists will usually accomplish their mission more quickly than you can, therefore making your mission a failure. Examples of this type of missions are M10 Chalet, Desal Plant.
