Point Targets are military targets which are concentrated in what can be considered a mathematical point, an infinitely small area which should be hit with munitions with extreme precision. Targets such as city buildings, and targets in the midst of many non-targets are considered to be point targets. When attacking point targets, weapons with only the necessary amount of spread and power are employed. For example, a single building in the middle of an urban city containing terrorists would not necessitate a thermonuclear warhead. It is also significant that point targets be hit precisely, as they are often located near other buildings which contain civilians and other innocents, therefore guided munitions are used to take out only the intended target. A strike executing in this manner is often referred to as a surgical strike
